approval

so for some reason I’m always upset and I guess I’m just sensitive to the little things that happen. This year his boy (idk him) who I thought was cute unfriended me on snap. I never really thought much of it. Then a close friend of mine blocked me which is really weird considering we were all cool that same day he did. I haven’t done anything wrong so what would cause them to block and dislike me and stuff. For some reason it gets to me a lot and I get upset a lot because of it. advice?
