So, I've found, that when it comes to somebody's skills or etiquette being lacking, people are quick to get like, unkind about things. And I was thinking like, we need to be able to talk about something that we think we might be doing wrong, and hear a polite response about how to do better. I want people to be nice to themselves and each other and maybe some people who are quietly disliked can wind up quietly liked? Some more love?

Like for example, people come to me with a scenario and it doesn't work out how I want, and then I have issues getting excited about their next suggestion or coming up with something of my own. Like, that initial disappointment fucks with me. To give an example that happens a lot: a guy will link to one of my many comments asking for a Daddy, say he wants to be my Daddy, I ask how old he is, he's like, nowhere near old enough to activate my Daddy kink, and suddenly I'm struggling to even remember what sex other than that good good shit.

Like this has happened so many times that someone it has happened with is probably reading this. Several times a day. And I apologize and have no idea what to tell you other than like, if you're at least 23, hit me up, I'll apologize, maybe we can play.

What I wanna know is, is there a good way to keep myself from acting all Depressive and shit if the first suggestion isn't on the money?

I've experienced similar issues of my mood to RP dying if something comes up that I don't like, even if the person I'm RP'ing with is understanding and willing to work around my fussiness I still can't manage to get back into the swing of things.
Honestly the best way I've found to avoid the issue is to RP with people I know to some extent and feel comfortable with, it makes it easier for me to relax and shrug off a misstep on either my part or theirs when it's someone I normally like to hang out with.

So maybe I should try to pep myself up through a few and try to get a few long term comrades with coitus so I have a handful of people who know my deal and my turn offs?

Maybe. What works for me might not be as effective for you, but it could be worth a shot.
And of course it you don't need to jump into RP'ing with someone right off the bat, you can start with friendly chats about shared interest, be they lewd or otherwise, and get a general feel for if they're the sort of person you think would be a good RP partner for you.

OMG that's an option!? I've had so many times I wanted to just get their vibe then I had a guy go "You ask too many questions," once when he'd been offering some goooood shit. I thought I'd been the rude one.

Yeah. it's a complicated process to say the least, there's a good number of people who are horny in the moment and want to get into the action sooner then later, and will get fed up if they're made to wait. Figuring out who is who can be pretty exhausting, and discouraging when it feels like you fucked up a good opportunity.
But believe me, when you do manage to find someone who you really click with, and they don't vanish on you after a few interactions, you'll have a great RP partner and possibly just a good buddy in general.

Thank you, I feel more confident now about dropping some kinky comments and reeling some people in. Maybe I should try and focus on some of my other kinks when commenting since in lieu of a profile those give people my vibes? Ya know, let people see more of what I'm into?

I’ve gotten a questionnaire prior to playing with a few individuals, asking about what I like, which helps and adds to the play (if you decide to play, that is). Just like physical sex, it helps to talk prior to it to see what works for you both.

Echoing what LustyDude4U said, it's completely acceptable to talk with someone and get a feel for them! Some people like to jump into RP right away, others like to have a good bit of set up beforehand to talk about kinks, limits, expectations, etc.

If the other person isn't wanting to talk or says you're asking too many questions, that's on them- heck, it speeds up the process a bit and makes it clear they're not gonna be a good partner for you. Instead, finding the people who are willing to talk and hang out with you, to share some details about what you're mutually interested in, that's important and often can be quite a bit of fun by itself.

To save yourself from the mood change, I suggest you remember RP is just roleplaying.
There's many kinks that require certain 'activations', but that doesn't stop people from RPing those kinks.
Let's say for example I was really into big tiddy goth girls. One BTGG really isn't needed, I can just ask someone to play one if so desired. They may or may not be a BTGG but at the end of the day I'm having fun and so are they.

Here's what I try to ask within the first couple DM's
Age, pronouns, kinks, turn offs, any comment or fav of mine they really liked(if they can't answer that I figure they are just DM'ing everyone all scattershot and whatnot), and if they care that the writer is trans(I say because it kinda adds to MY pleasure because like, we do fuck different tho).

Is that like, way too much to want to know?

Yeah, go for it! I'm sure there's plenty of people who read through the comments of a user before deciding if they want to message them or not.
You will of course end up getting a few of the lame "Wanna fuck?" messages as a result, but in the long run it'll be helpful to make your kinks easier to figure out for the more observant and thoughtful types.

I know, but like, with that specific kink, there's a certain situation I'm looking for that I think is hard for someone to just play. Would I be interested if a 24 yo could write and play really convincing 45 yo who gets why I want the 45 yo? Yeah. I just don't want to get hype then disappoint both of us if that doesn't happen. Because acting like you have huge tits is easy. I do it every time a bra is too tight. Hard to act 20 years older convincingly.

I don’t think it’s asking a lot. Seems easy and rather reasonable.

I feel like, so much more confident in doing my thing now!
