Is it really ok to cry on your birthday?

I’ve been so dang depressed for the pass couple months and i cant get out of it.

It’s my birthday today and I just feel so unloved. I go out of my way to make sure my friends and family have a special day and and all I get are those dry “ happy birthday “ messages. My boyfriend tried planning a surprise party and he had to change plans because literally nobody would of showed up. I moved into this new town a year ago and not having any new friends. All I wanted was my close friends to be there but nobody made the effort to come.. I just want to cry in my bed all day. I don’t know maybe cus I’m crappy person and nobody gives or idk what to do..
