Does anyone struggle with this too?

Is it just me or is socializing hard even on the internet for others too?
I struggle with thing as simple as writing a comment on a poste..
I'll sit down and and think "This time I'll do it! I'll just write a very simple comment and poste it" so I proceed to do so, I write the comment and delete it immediately...

I'm not sure what I'm scared off exactly but my head just tells me that I'm gonna bother them with my comment or that they'll think stuff like: "ew who tf is that weirdo??" which yeah wouldn't be the end of the world but still keeps me from meeting people..

I wouldn't even really know how to find people who like the same things I do.. I always just adapt myself to the people around me witch is getting really exhausting and doesn't build lasting friendships

I'm not really asking for help and more so wanna know that I'm not alone or that someone understand what I mean (Tho if you do have some tips on where to start with socializing I wouldn't mind)

Doing this alone scares me but I really want to know that I'm not alone

Anyways hope you have a good day/afternoon/night and thank you for actually reading this <3
