Hi,
Congrats on the sobriety. I remember that time well. Kind of a let down. The humdrum boringness of life has settled in and it kind of feels like " this is it?". You will get through it. Go to more meetings or read, read, read here. It's a bump.
I am sorry about the health problem. I can understand well. I have a precancerous condition that I have to get checked periodically forever and sometimes it's just depressing.
Now, no contact. That's a hard one. I went no contact with my mother last summer. Hardest thing I ever did. My mind started obsessing, I thought of calling her everyday. It consumed me for a good month. I constantly fought myself. But, it slowly got better and now I almost never think of her. It was in the beginning the most emotionally difficult thing I ever did. But I don't have a single regret.
Good luck in whatever you choose. And keep sharing
