I would like that welcome you to Healing Well depression forum. There have been a lot of posts about lexapro and about welbutrin. You might even want to read back about them. You might get more insight on the medications.
As far as I know, welbutrin is good for energy and motivation. It helped me with that issue. Also helped my thinking. And I did lose weight when I started taking it. So that might be an option for you. Did your doctor mention it to you?
I hope that you get some more posts on this topic to help you decide what to do.
