You don't just feel like you're sensitive, you are sensitive. I don't know what to tell you other than to simply toughen up. You can't just keep living your life getting butthurt over everything little thing then running to strangers on the Internet to garner sympathy. I'm not saying this to be mean either, I've been this person and still are struggling with my mental health to this day, just without the constant venting online. If you need help, I'd suggest reaching out to person people you feel are your friends, not the forums as a whole since majority of the people here don't actually know you or your struggles (for ex: your bf if he cares enough to even listen to you). It's a slow arduous process of trying to get better, but everytime you give into these feelings won't help
