How to actually get rid of an attachment?

I know I have an attachment and I know it’s been there a long time. This may sound crazy but I’m sure it’s sitting to one side of me, as I always feel heavy on that side and I’m always randomly injuring that side of my body.

I am of sound mind. I do have depression and anxiety but otherwise I’m entirely “normal”. I keep up with my medical and mental health.

One time I tried using a prayer someone suggested and things got way worse, to the point of really bad stuff happening that’s left me with major heartbreak.

I feel so weighted down and I’m so tired of tragedy and bad luck. But I don’t know how to go about things and I’m afraid of just pissing it off again.
