Just Confused's Things

Why does talking to someone whos done something disgusting, and borderline evil, make me feel nauseous and feel sick?

Btw i say evil because this person i a convicted pdf. But he has done other disgusting and disturbing things but thats one of the worst ones.

But he messaged me earlier and i havent spoken to him in years. I didnt even realise he followed me on social media, but like my only words i said back to him was 'not so kindly fuck off you disgust me'.

I cant stop the feeling of disgust i wanna cry also how do i stop this?

so i go through a phase of liking different tagged books, from rivals to deliquents, to secret relationships, to single parent. the list goes on.

but i really want a best friends sibling type manga/manhwa/manhua.

but i cant seem to find any at.

idc if its straight gay or lesbian. ╥﹏╥
