I would look at resources in your area. If there is a prevention hotline where you live, they can usually offer better advice than I can.

Outside of that, what really helped me was accepting that my brain was trying to attack itself, and that I needed to be aware it was fucking with my perception of reality.

If your brain is doing bad chemistry, sometimes meds are the only thing that can help. I forget to take mine sometimes, and when I do it is usually a week before the old feelings start coming back. Talk to a doctor.
