I am suspicious of Wellbutrin and its long term effects. I am not just "anti-drug"--I take some--but I am particularly suspicious of "anti-depressants". I feel this MIGHT be making you worse.

However, the circumstances of your life are very trying. You have been removed from several of your key life supports, including your mother and your former neighborhood.
Your husband may be a very supportive person, and worthy of respect, but he doesn't talk much, so you don't have someone to talk to in your new environment.

I don't have any specific advice, as I too am lonely (a widow of two years) and mostly without friends, as I can't get "out" much any more. Life has become negative, but I find that as the physical world becomes more negative the inner spiritual life is increasing.
