I don't know what to do.

First you need to get your wife to the Dr. They can give her something to calm alot of that Bi-polar down. If she drinks she needs to stop, it just makes it worse. But one way or another you need to remove alot of stress from your life.
good luck
The treatment of bi-polar is a cocktail of meds. Alot of bi-polar folks, myself included, can not be treated with the meds. It is not the anti-depressants that are the problem, it is the mood stabilizers. I have been on several of them and can not tolerate them. The old standby, lithium, is more or less nothing but a salt. I was up to about 1/2 of the dose necessary for it to work and had to stop, I was constantly drinking water and on the throne. Very easy to go toxic on. Several of the others just bought on various side effects, which just meant more meds that I could not tolerate without the suicidal thoughts, insomnia, constipation etc. Giving anti-depressants to a bi-polar individual with out a mood stabilizer, well, that is when life got interesting. The anti-depressants did nothing but trigger a near non-stop manic stage. My mania is rage and agression. Most of my more "memorable" episodes in my past were when I was on just an anti-depressant. Flipping out throwing tables thru walls, blowing a steel frame door off of a concrete wall with a 1800 pound container of mail, stringing people up by the throat. The good old days. I got lucky and found a psycologist that was able to get thru to me. He helped me understand what it is that is wrong with me. And once I hit rock bottom, put a .357 in my mouth and pulled the trigger (go figure that one round had a bad primer) and got divorced I made the decision that things had to change. Once I found out what triggers my manic episodes, stess, I just did my best to stay away from it. For the most part I don't argue with people at all. I just turn and walk away. I argue, no matter if I am right or wrong, and I normally black out and then goofy things happen. I have been seeing head docs for close to 15 years now. From what they tell me that there are alot of bi-polar folks just like me, that just can't tolerate the drugs. I made the decision that just because my chemistry set is busted it does not give me the right to ruin your day. I have a friend that I used to work with that is just like me in regards to the drugs. Looks like he will be losing his job with the PO after 28 years of service. Point of the last statement is I am not alone in the inability to deal with the meds, Jeff has tried alot of them with the same results I have had. It is no big surprise that bi-polar folks self medicate with alcohol. I did years ago. This is truly one of those things that if a person does not want to be helped, they can not be. So taking a bi-polar person to a doc to get meds just does not work. This person has to want to change there ways. Often times hitting rock bottom is the only thing that will trigger the desire to change your life. And then you have to hope that the meds can be tolerated. Bi-polar folks tend to be good at hiding it. I met a few members from here, and they no doubt thought I was a completely normal guy, right Justin? I have learned to hide it, sort of put on a happy face and go thru my life. But ask me how many nights I pace the floor, unable to sleep because my brain will not turn off. Or the nights I am sitting outside, watching the stars listening to the guy playing bag pipes (it is just in my head). I truly appeciate my wife. Sorry for the length of this, I just felt the desire to comment on the above post.......
