Am I Depressed?

Anonymous
I was chatting with a really close friend of mine yesterday, who I have been talking to for years almost on a daily basis. She asked me what was wrong with me, and I was like... dafuq? And she told me that I haven't really been the same, been sleeping way too much, been eating too much or too little, haven't been doing the things I used to love doing, and have been half-assed when it came to communicating with people and socializing. She asked me if I was depressed. I was surprised, I had always considered myself an okay person who had bad days and shit. But apparently I've been having bad days for an extended period of time, and I didn't notice how much I've changed until she brought it up. She asked me if I could do an online diagnosis, just to make sure. I did, only for the results to come back positive. Apparently, I have anxiety and severe depression. I did many, many tests, and the results are synonymus. I don't know what I should do now, if those results are reliable, and if I should go to a professional to get real results. However, I'm only sixteen, and I don't want to have to bring it up to my mom. I don't want her to think I'm being petty or overdramatic, but I'm just really helpless right now, because I admit that my moods have been getting worse and I get pissed at people for no reason and I just hate the person I'm becoming. Help?
