Should I tell my crush my past trauma or not yet?

So I’m 23 and I’ve had a very difficult life and I have my ways to cope up with the trauma I’ve had which involve hurting and hating myself. And my crush just said she likes me back and I’m wondering should I tell her about my past and my self sabotaging problems before dating or should I wait?

I really do hate myself and do hurtful things to my body in order to live so she’ll probably freak out and leave me. But I love her so much and I know I don’t deserve her so she should leave me. Idk what to do now really
