I have the same issues. I was diagnosed with Bipolar and Severe Anxiety Disorder about 5 yrs ago, and have been up and down... from being on meds to stopping the meds .. and now I am back again because its really taking a toll on my relationship with my hubby. He just started a new job last week after being home with me for 6 months. Even though I DO trust him, I went on three rages in a matter of 4 days... each one lasting 6 hours or more. I accused him of these ridiculous accusations that I made up in my mind that aren't even true. I hid his driver's liscense, threatened to destroy the car LOL hid the car keys, and told him that I was divorcing him if he went back to that job again. ALL OVER NOTHING!!

I have really struggled with accepting the fact that one of us has to work to pay the bills, and I am in no state to do that. I got too used to him being at home with me, and even though I know he loves me, and he will never leave me, and he has never given me reason to think he would do something like that, I still for some reason, have these crazy thoughts.... and I hate it with a passion!
When my Mom accused me of just being jealous... I realized after sitting and talking it out with him after my rage, that it truly isn't jealously at all.. but rather fear. Fear that all the crap that I put him through is gonna drive him away. Altho he has assured me that he is in it for the long haul with me, it is still very hard... and something I constantly think about. I spend most of the day getting rid of these stupid thoughts that my mind creates. It's the feeling perhaps that I feel that I am causing him so much stress with all this and that he is going to go off and find someone "normal". Silly, I know!
So, I do know what you are talking about!
