Relaxed atmosphere symptoms and conditions

I've been on Wellbutrin for about two months. I notice that I am quick to anger, and seem to suffer memory loss. I was beginning to think I was in early stages of Alzheimer (I am 45) as it runs in my family. I couldn't remember names and it terrified me. The doctor subscribed it due to the weight gain I experienced on Prozac, and I have lost weight on Wellbutrin. I have been diagnosed with mild to moderate depression, due to excessive crying that I could not control (especially at work). The Wellbutrin has helped keep my crying under control when crying would be inappropriate. But still feel it is excessive when I am in a more relaxed atmosphere. Prozac was certainly my "happy pill".
