What do you want to work on? And you can't say work on getting my wife back.
Therapy is for you. What do you need to fix? Do you have childhood issues? Trauma? Addictions? Compulsions?
I feel terrible. My moods swing constantly. I sleep in chunks of 2-3 hours every night I've lost 20 pounds in a couple months.
SAdly, that is normal. Don't be embarrassed to seek medical help with the mood swings. Things can get overwhelming,believe me, I know. This situation is probably one of the worst situations you will ever encounter.
But the good news is that it will get better, but it does take time. And it is going to take as long as it's going to take... In my case it took 6 months after BD before I started feeling better and another 6 months before I could say I was well.
Physical activity helps, a lot, esp. hiking in nature and in the sun. Also trying new stuff helps, meeting new people helps (not women).
