Dom, Congratulations on your engagement!! And I totally agree with Anna. Please don't give up on antidepressants until you find the one that works for you. This is a chemical imbalance and each person reacts differently to various medication. Sometimes it just takes a little time to get the right one. Please keep the communication lines open with your doctor. I've been in the same place you have with this and truly, if you keep trying and work with your doc, you will find the right match and it will make so much difference in the quality of your life.
It's funny, I haven't been over here since the last time you posted, but for some reason I was "called" here today and there you are. I've been thinking of you and sending lots of positive thoughts for wonderful new beginnings each day for you and Kate. Keep moving forward. Changing yourself takes time and commitment but you are SOOOO worth it!
