ERP Question

When does ERP stop making things worse?

I started ERP with my OCD specialist last year, but he stopped because I became suicidal then referred me to another specialist to do trauma work first. Turns out she was giving me reassurance so I begged my OCD specialist to try again.

I'm two weeks in, doing "2 minute drills" and basic at-home exercises, but I'm getting worse again. I would kill for a modicum of relief. None of the meds I've tried (and I've tried them all) have helped except for lithium (which I have to go off of the because it's taxing my kidneys) and Valium (which I can't take because benzo).

How did you push through the beginnings of ERP until you felt more in control? The last time this happened my psychiatrist recommended in-patient.
