Is Wellbutrin Xl Right For Me?

The last few months of my life have been chaotic for me, in a short recap I lost my job, lost my transfer to a new town, broke up with my boyfriend, spent a ton of money on things that didnt provide me any satisifcation, and have moved about the country being dubbed a "couch monkey" by a friend of mine. About three weeks ago I was sitting in a movie theatre in nyc and my life seemd to come to a head. I cant recall the movie I was watching but I know during the movie I was lost in my head, couldnt focus and had a general funk all at once rather than separate incidences which was more common.

I attributed it to a lingering cold but looking back over the course of the last few months I opted to see my doctor to discuss it. Intially, I wanted to discuss with my doctor going back on attention deficit disorder drugs like conscerta or strattera. I'd been on ritalin most of my life and while it was effective when I was younger, I was taken off the pills in high school. Occasionally through college a doctor would think that ritalin was needed but I disagreed and refused treatment. My doctor said I was depressed and prescribed wellbutrin xl to combat my depression and to aid in quitting smoking.

I've been on wellbutrin xl for two weeks and have not seen any improvement. Rather, my laid back carefree personality has become increasingly agitated. Where I used to be slow to react, I find myself being more confrontational. Further, I have a constant headache, feel largethic, sleep more than I used, have no appetite ( in fact I force myself to eat only when around people so they wont think i'm anorexic), feel cloudy most of the time, in general have a hard time carrying on a conversation with my friends and family, and have seen no decrease in my smoking. Is this supposed to happen? Do I need to ride it out for two more weeks to see if it passes or should I be calling my doctor already?

I've never been on antidepressants before, except they once prescribed zyban a few years ago to help me quit smoking but I stopped that after a week because I had a cloudy head and felt over excited all day long. I'm not averse to taking to a pill, so i'm not looking to quit a treatment plan. I figured when my mood stablized I would seek an exercise plan at a gym to increase my stamina and energy and then alter my diet to eat healthier. Im just concerned about the changes i'm seeing in myself. Any advice or feedback would be appreciated.
