A baby has nothing to do with resolving your depression issues, I'm afraid. And medications aren't the best way of resolving them either. Once on medication most of the time you get more and more addicted to it (unless you have hormonal disbalance or something like that); and then once you stop meds for even a short time you feel even more depressed. A much better way of dealing with your depressed moods is seeing a counselor, someone who you can "talk off" your problems with and who will give you a good piece of advise as to how to overcome the issues making you depressed..
