insecurity drives me crazy.

i feel like something’s wrong with me, i 100% feel like everyone hates me, finds me annoying, talks about me, and when i look in the mirror or see pictures of myself i feel disgusting, i hate it so so much and i don’t know how to make it go away. all i want to do is love myself but no matter how hard i try or want to i just can’t. i feel like my boyfriend will find someone else, that my friends don’t care about me or want me around, and i honestly don’t have any family. someone please tell me what i can do to get rid of this feeling :(
