Depressed

How did any of you deal with your depression I was depressed before I got pregnant and after I had him it just got so much worse I don't make much money so I can afford health insurance but for some stupid reason I make too much to get health insurance through the state (all I have is emergency coverage) I just want to be happy again and no matter what I do I can't. And talking to someone isn't helping I've tried friends family and my boyfriend and nothing's making it any better. It's getting to the point that I have to tell myself that jumping off a cliff isn't worth it and that's at least 3 times a day.
