Feeling skeptical, but trying

I've been struggling with depression for 23 years. For the last 5 or so I've been on zoloft and that has helped, but lately I haven't been feeling okay at all. I find myself wishing I could die almost daily. My husband doesn't help either. He gets really annoyed at my "bad mood". Today he told me he hates me. We've been married for all of our adult lives--we were high school sweethearts. I have never talked to anyone about my depression, and sometimes I feel so desperate to just spill it all out. I don't want to burden (or scare) my few friends by letting them know my feelings so I thought I'd try this online group. I am skeptical that it will help, but I gotta try something.
