Relapsing

Even though I'm in therapy, I find myself continually relapsing recently. I know part of it is my BPD and some serious personal stresses that's happening right now and I know the ED is just a reassuring way that I have some control in my life. But what do you do? Focus intensely on a hobby? I've tried reading, yoga, running, watching movies/TV but I can't distract my attention away. Once I start thinking and getting stressed out, I feel like I'm completely disassociated with myself and my body.
