Am I depressed or have anxiety or is this normal for a teenager?

I suffer from anxiety/depression and I've experianced many symptoms similar to yours. I go to therapy and it really helps me to cope with these feelings. I think it's be best you talk to someone about it like I do, get to the root of this problem and deal with it in a healthy way before it gets to out of hand. I got into drugs trying to escape my depression and it only made my life worse, I've been through many truamatic events and even when things are good in my life I feel upset for no reason. Get help dear, good luck. (:
