Ksman: We have a young adult child with perhaps similar issues as you describe; but fortunately, she does not live at home and is doing fairly well at this time. It is a VERY difficult situation to be in. (Understatement of the year, right?)
One positive from your post that I see, is that it seems your son is willingly going to the doctors. Does he also go to weekly therapy? I know this is going to sound strange, but if this has been going on for a long time, I would consider getting therapy for you and your wife (together) to develop a plan of action. Such things are horribly difficult and it's hard for anyone to formulate a good plan, nevermind two people who might have different views on the subject. At some point, your son should probably move to another house and this is going to be tricky. If you are fortunate, he will be able to find a job and perhaps share an apartment with a friend, etc. If he is too ill, at some point, he might have to get on gov't disability. Take extra good care of yourself and your marriage. Eat well, get in some exercise, take your vitamins! Consider visiting a local NAMI meeting for more support or ideas.

HOPP: oh my!! I'm so sorry that you have HMs! I know someone with these and they are very very difficult. Sounds like you have a nice arrangement though living close to your folks and with your fiancé. It's absolutely fantastic that your realize that some days you are not yourself and can be "off." No doubt your parents have been helpful and wish to be helpful. As best as you can (no doubt it is crazy hard), try to be aware and put your best foot forward and be as calm as possible. Maybe you can get one of those emergency call buttons, if you don't already have one????? You are so fortunate to have this set up....having parents close by...try to concentrate on this. Wishing you well.
