You need to focus on yourself. Depression is a serious problem and it sounds like you have a lot of work to keep doing on yourself. Talking with an IC is a great step. Do you have any short term goals (about you, not the R)?
Also, why did you move out of the house rather than her? I ask because I did the same thing and think it was a mistake on my part.
Hang in there. You will get some great advice on these boards. You might not always like it, but it will be honest and helpful if you really listen.
