You can find a clinic that will take you for $50 or so. It's not the cheapest of options, but it's the single most impactful choice you can make in your situation. If you adhere to your schedule, and if your brain chemistry matches my own (which it might not), you'll start to be "evened out" after 30 days.
You have to take the pill every single day though, without exception. I almost didn't realize the Prozac was effective at all, because the first time I tried it, I was inconsistent.
People seem to hate this advice and reply aggressively each time I give it, but the moment I see "clinical depression" I will continue to give it. If the doctor notices any problems, they will take care of it.
