I can TOTALLY relate to this! I also went on Wellbutrin for about four months.. at the time it was to quit smoking. I was running at the time and I was very, very proud of the six miles I worked my way up to. Shortly after the Wellbutrin took affect my six miles quickly become eight. then ten. At the peak, I was able to run 16 miles!!! But there was always some funny feeling while on it. It would be like "waves" of emotion that really haunted me. I took myself off of it and really struggled to try and keep up the mileage. in the end, I could not keep up the mileage without it and it dropped back down to where I felt I would be lucky to run six miles. I was so so mad that I quit running altogether. The zombie like state in depression.. oh yes! My wife says I dissapear. It's still me on the inside... but I can't seem to get "me" out to others around me when I am like that. I get secretive, even a touch on the paranoid side. I find I really have to be careful when that happens. It's like me against the world. On the "up" times I have a lot of anxiety. A whole lot of it. I was trying to gauge how "manic" i was based on my anxiety levels but the other night my anxiety failed me. I had very little and I didn't realize I was shouting and moving a mile a minute. I hate that. But it does move very quickly to the other side, and back, and over again. I am told I am all mixed up. My moods are both on the mood chart, being on the high and low side at the same time. It's confusing when I fill out my mood chart, looking at both sides and being sure of what I record. I take a while standing over it to fill it out. My wife tells me this: "You have your absolute high and low limits for the day. This is your mood. It's not the same as your emotion. Your emotions are like a needle that travels along the line, and the needle can travel rapidly. When you are depressed, and your levels are moderate or higher, lets just call that 'actively' depressed." This perspective has really helped me. Maybe it makes sense to you?
