This is probably a very generic fear, but
I have the fear of being alone, and having no friends, i honestly think that everyone i know and that i personally care deeply about hates me, i don't know why, i had ONE friend who said that people lie to me when they say it's okay and they said that many people asked why they were my friend..... long story short i don't wanna be alone and I'm scared that everyone i know will get sick of me
