Treating my mood swings naturally?

I am having a problem with depression. I was diagnosed with depression and a chemical imbalance when I was 11 and was put on Zoloft at that time. From that time until I was 18 I was put on many diferent meds and started to cut on myself and was hospitalized 4 times. When I turned 18 and stopped the meds I felt so much better, and I promised myself I would never take them again. It was my choice to stop them becasue I never like how they made me feel, I felt worse, not better. Now I am 21 and married for 2 years and just recently my depression has come back. iwant to know how to treat it without pills. I have isolated my husband and friends. I am parioniod that everyonw thinks I'm stupid and is talking about me and laughing about me. I am verbally abusive towards my husband. These symptoms have just started a few weeks ago. I love my husband and I know I will lose him this way. Has anyone ever had this problem? Can You give me advice on how to overcome this?
