I just want to say what a wonderful, loving hubby you are to put your issues on the back burner for now, just to focus on her mental health issues and getting her mentally healthy. I hope that when she is well adjusted with her medication and all, you two can focus on finding what works for the both of you regarding intimacy. Who knows, maybe it'll all fall into place somehow when you have the majority of the pieces in place from solving the bigger issues?

Either way, I commend you for your loyalty and devotion to your wife. A lesser man might get to the point where his frustrations boil over and he walks away from the marriage. Not you, you take the vows you made to her, to be there in sickness and in health, for better or worse, etc to heart and are sticking by her side. I can only hope to find such love someday.
