I think that different anti depressants work differently on many people. Just because it doesn't cause many people to gain weight, doesn't mean it is that way for everybody. It sounds like you need a different anti depressant. Maybe when you are done breast feeding.
Let your doctor know what happened, even if you have to point out that he was wrong in his assessment.
Best wishes to you for a wonderful day.
