Feeling sad and insecure

I keep reading things online, on here (reddit), tumblr, and twitter and so many different posts and comments makes me feel like I can't fit in.

Many different aspects of my identity makes me feel like I'll never fit in ANY spaces, let alone LGBT ones, or inner LGBT spaces like being butch and/or masc.

I question if I'm masculine enough, if my body is OK, being a BIPOC, my attitude on life etc.

I know I shouldn't feel this way and that there are lots of people like me but I can't shake these feelings. I know they stem from my own insecurities, but am I so wrong for wanting others to validate me? For wanting others to like me?

I've been seeing other vent posts so I guess I felt a little bit inspired/encouraged to make one of my own since I've been constantly feeling really upset.
