Yes, that makes sense. It sometimes happens to me too, just because either:
I think that someone will interpret what I say as offensive
I think that I will get shamed
General social anxiety stuff
Absolutely no reason at all
I don't like to play favorites but...
I mean my mood improves when I read your posts, so you're definitely not spreading negativity here.
The only thing you could do wrong is to not talk to anyone.
And by posting about your own problems, you not only receive answers and get things off your chest, but also voice problems that many other people deal with and are too scared to explain.
The act of typing my response here is helping me to understand more about myself.
EDIT:
If you don't mind me asking, when did your pronouns change to they (u don't need to answer if u don't want to)?
