Most of the time I feel "normal" however several times a week I will feel like everything's great about life and I want to eat healthy, be nice to people etc. Other times (usually not as often) I will hit an absolute downer, be convinced the world's an awful place and even contemplate suicide.. ok re-reading that sounds a bit too dramatic :L.
I know this might be normal as I'm a teenager, it just doesn't seem like your regular "put it down to hormones" thing. It doesn't seem like manic depression either so I don't know what to think! Is this normal?
