Hi, I am a 39 year old woman, and have been basically a happy fun loving person in my life. I have been depressed before after a break up with a boyfriend, and normal things like that. My concern is that every once in a while, someone will say something that I may not understand even a harmless statement, and a few days later I will start dwelling on it until it controls my mind.. I ususally find a way to snap out of it and I go on with my regular routine and am happy, but im wondering if I may have some sort of chemical imbalance, because when the thougth comes in my head,, its usually a few words someone said,, I will play it over in my head and I can't function like I normally do because I keep thinking about it... In the past few weeks its got to the point were I am depressed, not enjoying doing what I usually do,, and I snap out of it from time to time but the obsessive thought creeps in ,, its like a mind game... I am living with a man,, I moved to michigan from mass a year and a half ago, and I dont want to ruin our relationship because he doesn't understand why I keep dwelling on stupid things, and now im depressed. Does anyone have any advice for me... Its like I won't let myself be happy sometimes and on top of all this, I quit my part time job that I have been at for a year because the new supervisor was a jerk, putting it lightly.. I was happy there, and thats only compounded the problem..
