Out of place

I just feel so out of place here. I mean, everywhere on the internet, but i just have 0 clue what I'm doing on Here. The two main groups of people are Adults who know how to talk to eachother with longform forum content and Kids who are used to twitter/tumblr.

I think its easy to guess that im neither. Its rough because I don't even know where to start, because of the rejection sensitive dysphoria. Its not like I can just Try Again And Again.
