depression and wanting to have a 2nd baby..

So i have major depression and anxiety (im already on medication for it) and things haven't been goin so well here lately but i have baby fever sooo bad. Our daughter will be 2 in June. Honestly I didn't want more than a 2 year age gap between kids but things happen.

I guess what im trying to ask is if anyone has suffered from major depression and anxiety and decided to have a 2nd child? If so how bad did it get? I should also add that i struggle with infertility and have other health problems as well.
