I disagree with the people who are suggesting that you're bi-polar or that you've discovered that being alone is the secret to being happy. Some people are bi-polar, some people are just happier on their own, but I think you'd be experiencing far more happiness (at least at times) if either were the case.
It does sound like you're finally beating your depression. A fair number of people just cope with depression using drugs, which are meant as a crutch to help deal with it, but don't solve it by themselves. Some people, like myself, just beat it in the due course of time. I had to hit rock bottom to do so, and I've known other people who've done the same- you get pushed to the edge, you lose everyone around you, until you realise that you and only you are the only one who can chose to make yourself better. Sometimes it does just take losing everything to turn it all around.
The thing I'd suggest that's worth doing is reinforcing the happy moments. Contrary to popular belief (at least, when you're not depressed) your emotions can be manipulated by yourself. Your facial expressions are intrinsically tied to your emotions- just smiling actually activates certain pathways in your brain associated with happiness. Doing things you love, playing upbeat music... you get the idea. A lot of people are in the bad habit of feeding their emotions, especially the negative ones, and it really helps to realise you can break that cycle.
