How do you guys cope with and move through shame?

I feel like shame has been a major part of my recovery work since I started in Therapy about 5 years ago. I'm still uncovering and moving through layers of it.

It seems like in therapy I dealt with what I was comfortable with....and that gradually grew to things I was more ashamed of. Now my current therapist is making me focus more on things from the past that I haven't fully dealt with yet.

The thing that I'm now working up the courage to tell her is that I took diet pills for a few weeks over five years ago, very soon before I had a psychotic reaction and was hospitalized for a week. I have never really talked about this with anyone. She was asking me this week questions about that time and if I was on medications. I didn't tell her about taking these pills...But the fact that she cared enough to want to figure out why I had that psychotic reaction really meant a lot to me, and I think I want to tell her about it in the future. But I still have so much shame over taking the pills in the first place. I know it was a really stupid decision, and I regret it.
