Looking for non-medical treatments for my conditions

Therapy, especially look into DBT. It gives you concrete tools to deal with your mood changes.

I know in some area you can find a homeopathic doctor that will treat you with natural remedies.

If it's depression you could be on tons of stuff. Zoloft and Cymbalta have worked best for me. Cymbalta helps with pain relief. Zoloft is also an anti-anxiety, so that (may) help you sleep. I don't know much about insomnia specifically, however, I do know I get really sleepy on my anxiety med hydroxyzine. Plus, it doubles as an anti-histamine. And, there's always melatonin, or cbd for sleep. Or, otc sleep meds. You see them on TV all the time.

Which condition?
