Sweetie, I can't imagine even the most hard-hearted social services person coming down on you for getting the help you need. I would think it would be a positive thing on your side!
There are some meds that are reasonably OK to take while pregnant, I think -- definitely do check with a pdoc. It's a crapshoot in the end, really. I did everything right, and my boy still was born with a (very, very, very minor) birth defect that had absolutely nothing to do with my diet or meds or anything.
