I am so sorry to hear that you feel like this and wish that I could offer you some advice but I suppose everyone is different. I do tend to get depressed but not so badly as some

When i do I try to relax by listening to music and reading or going for walks. Being involved with people i thnk is very good therapy, just laughing or talking..it does me good

I hope things go well for you and you do improve. Best Wishes

Some people are also just genetically predisposed to it, too.

It sounds like a bad thing, but operating in a state of "just ignore it" is not a terrible practice.
Also, don't worry about tomorrow, next week, month, or year. Just... now. What are you doing NOW. If you're not happy (or at least content) doing it, stop, and do something else.

Well, I was able to recover myself from depression without any medications. I have shared a post about that. I hope this will be helpful to you too.
