Medication for depression?

For the first time in my life, I’m thinking about trying to take some medication. My severe downs are really starting to wear me out and I don’t think I can handle much more of it. I’m beyond “sad” and have been at this point for a while, I’m on an extremely short fuse – everyone is pissing me off. I have no one to talk to, no friends, no anything. A little voice in the back of my head keeps saying, “Fuck it. Nothing is worth it. Give up.” I honestly don’t know how much that is the depression talking or it’s truly becoming my overall outlook.

The thing is, I don’t have insurance. I’m already in debt for medical bills and I do not plan on furthering that debt. What the hell are my options? Anything?
