Karilann,
The problem with wellbutrin is if anxiety is involved it can cause that symptom to increase. I can't take Wellbutrin for that reason. Prozac makes me a zombie and a complete couch potato...no energy whatsoever.
Anti-depressents can be a trial and error to find what works best for
you.
It is possible some of what you are feeling could be related to perimenopause.
If you keep track of your cycle you might find a pattern to some of your sadness. I am almost 50 and have started having moods swings, crying with no known reason, and random sadness. I have dealt with depression in the past...this does not feel like depression. I have started taking a Phyto-estrogen (natural, OTC) and I think I am seeing a difference but need more time to be sure.
Your mothers death, feeling isolated due to the move, a husband who does not communicate or like to go out and the possibility of perimenopause...who wouldn't feel sad and unhappy
Talk to someone...your doctor, therapist, psychiatrist.
