Be proud of yourself that you stopped SH for so long! If you did it once you cand do it again. Old habits are hard to break. Just b'c you relapsed doesn't mean you can't stop again. Ik you have been struggling with this for years. Give yourself some credit for stopping. Remember that you can change something that drastic so quickly. It takes time.
To me this relapse is just a bump in the road. You have to keep going! I'm sure your T will help things instead of making them worse. She's there for you!
Your dear friend,
Hoping.
