I needed to go on an AD as well. As Miguel's Mom mentions, lowest dose to start; my doc even had me take it every other day (as it was a med that could not be split in half so achieved the same result) when I first started to be safe for the effects, tapering into it, and then worked up to daily. It made a world of difference to help with the depressive symptoms, with no ill effects.
Wishing you well and hope you find the help you need.
