Attachment Issues?

Hi ladies!

I am coming on here bc idk where else to go for advice. But anyways, basically I feel like I have trouble getting attached to anyone in my life and if I do, it’s very short-lived. I’ve always been an introvert but I also have been through a lot of stuff in my life which made it worse. My grandpa died of cancer when I was 10, I lost 2 cousins due to drug overdoses, I lost a friend since middle school to a car crash, my uncle committed suicide, my dad became a heavy alcoholic, I’ve been cheated on, sexually assaulted, manipulated, used, lied to, and so much more and I’m not even 18 yet. I’ve been with my current boyfriend for almost a year and I love him to death but lately I feel disconnected at the same time. And I know it’s me bc I feel that w everyone at the moment. Idk what’s wrong w me
