Self harm and Eating disorder

So I don’t know how to start off. I’ve been self harming and dealt with anorexia since 6 grade (I’m in 11th now) , but I did have some clean months throughout the years. Well I started a few months ago, I started off cutting but now I mostly burn myself. With the anorexia issue, I stopped in 8th grade and managed to be good for like 2 years when I started purging. I really don’t understand why I do this, and it gets me really upset and frustrated which kinda causes me to burn myself. I just, i want to get better. It’s just hard. I have a therapist but I can’t really talk to her, we had a sort of contract that promised she wouldn’t my parents my issues unless those issues involved me hurting myself or others, but she blabbed our other minor issues and so I don’t trust her anymore. I try talking to my friends but they don’t care, and I understand they have their issues but it also upsets me cause when they have issues I help. I’m blabbing now. I just want help guys. I want to be okay.
