Call your psychiatrist and ask him why you aren't on an antidepressant. I'm sure he has a good reason. He knows you. He's treated you. You've said you like him. I assume you trust his clinical judgement. ECT is a complex treatment.

It's unfortunate you are ineligible for an FMLA. Mine saved my job. I had rapid cycling (an episode of mania with psychosis) every 8-10 weeks for 2 years. I was repeatedly hospitalized sometimes for as long as 8 weeks. Every year my psychiatrist would renew it. I was able to get intensive treatment and stay employed. A lot of people don't know FMLAs are available for people who have worked a year and are full time employed with serious illnesses. It's a real blessing.
