I am new here and wish I was as wise as some of the members that post here and could tell you the best way to do things but I'm not. All I can say is i am in a very similar situation (I'm 30 and my wife 25 just walked out). I have taken away a lot from reading others posts and has helped me take a totally different approach than I would have if I didn't come here.
It is a very tough time for you but it sounds like you a getting further along the road of moving on if the thoughts of getting D started are in your current thinking.
I hope you start to feel better soon. I know it's life changing and I'm definitely not the same person I was 2 months ago. Stay strong Tyler
