Its a difficult position to be in for sure, and I'm glad that you found the ambition to post this.

I would definitely see a doctor about adjusting your medications at the very least.

If you live in the US work is required to offer insurance now if not you can find "competitive" rates in the government marketplace.

Finally it sounds as if you might need a change of pace. Start looking for a different job perhaps. Or when/if you get some down time help by volunteering. One of the few sure ways to lift a depression for me is by volunteering my time.

I hope you feel better soon.
