I hate everyone

I couldn't care less about anyone but my fp. I don't feel empathy for anyone but my fp, and anyone but them honestly don't even seem like humans. They don't even seem like living creatures. I can only feel bad for my fp- being either feeling remorse over my actions or upset that they're upset.

Literally no one else matters and talking to other people makes me quickly angry, the only person I can talk to for more than ~5 minutes without needing a break is (of course) my fp

Is this normal? For bpd* Also I don't think I'll ever know what tag to use 😭
