Mother's Day present? How nice. I didn't know you celebrate it so early - it's second Sunday in May in the U.S.
I would never call you crazy for taking the meds that you are. As long as you're aware that depression is a possible side affect, and you do, and you're keeping that in mind.
Do you attend church at all? That's a great place to find support and also a possible place to make some new friends, and possibly starting some new activities. Just a thought. My church family was/is a huge support to me through everything.
Also, please remember that the main point of DB'ing is to save yourself, grow yourself, improve yourself. In doing that, if your marriage is saved - great. But if not, you're ready to start over.
I hope you have a good day. Keep up the good work.
