I agree with CL,
You do need some new activities and maybe even some new friends.

I don't think my married friends would have gotten me through my separation/divorce. I think you need to find single friends and start thinking and living like you are single (I don't mean dating, but healing as a single person).

P.s. I hear you about the appetite! I find I have to work very hard to stay "sad" and keep the weight off.

There is no arriving, ever. It is all a continual becoming.
