Welcome to Mayo Connect @brightcloud. What a gorgeous name! My sincere condolences on the loss of your husband. I hope that with time you will begin having only happy memories, not only sad ones.
I'm wondering if a special light to help seasonal depression help? It sounds like you are living somewhere where you do not get adequate sunlight. I'm not trying to sell you anything, because we can't on this site. However I've heard that these lights do work.
Please read back on the posts, if you haven't. There are some wonderful suggestions.
I'd also like to suggest two groups that you might be interested in:

I was lucky to not have had problems with weaning off of Effexor but a lot of people have as you will read in this group. Have you considered CBD oil and have discussed trying some with your doctor?
