But then I worry that I do have a drinking problem, because being depressed I often drink just to feel good enough to do anything, besides just watching tv, or just to shut up my overactive mind.
Yeah, if there's no one you hang out with, it's a given that any drinking will be done alone. I wouldn't worry about it too much. I drink a couple glasses of wine every night while I watch TV, mostly out of boredom (and I like the taste of wine).
Drinking becomes a problem when it literally becomes a problem - you're missing work, disappointing people, showing up drunk at events, get a DUI, etc. Watch the show "Intervention" to see some graphic examples. Alcohol becomes the focus of an alcoholic's life, and they feel powerless over it, usually with some sentiment to the effect of their life "spinning out of control."
Having a few drinks by yourself isn't in itself anything to worry about. When the day comes that you screw up at something, and the answer to "why did this happen?" is "I got drunk," then I'd start to worry.
