I think I might be depressed and I'm really scared what should I do?

Hey thanks so far!

I don't even know what my symptoms are, I feel as though I'm overreacting and need to get over myself? Or I'm being paranoid? I'm just really scared and I don't know what to do

Like what have I got to be sad about, sort of thing even typing this feel extremely silly but I don't know what else I'm supposed to do?

As for exercise I bike an hour a day, the only TV I watch is supernatural and I volunteer at a hospital. I don't buy the "happiness is a minute by minute choice thing though because I certainly do no
