I am currently breastfeeding and would like to take a natural antidepressant.. can i take sam-e.? if not ..any recomendations?

Best not: There is a lot of research on antidepressants and breastmilk, but it is not complete. With sam-e, unfortunately there is not much known, so to be safe, you should avoid it. But maternal depression itself is known to be not good for for infants. I would check with a skilled practitioner and list all the safe ones (both naturally occurring and not) and weigh the pros and cons before you decide.
