Am I depressed or am I just "going through a teen phase"

My psychologist tried to diagnose me with depression a few days ago, but I didn't want to take medications so I made my symptoms sound less severe to avoid being prescribed medications. So, before you say something about self-diagnosis, just remember that I was going to be diagnosed before, but I prevented it from happening.

Just at the beginning of the school year, I was fine. I had friends, liked going to parties, and did things that any teenager would do. Few months later, I started isolating myself. I didn't really enjoy being with friends anymore, so I just started ignoring them. Now, I've become more silent and emotionless. I barely talk at all anymore and even when someone tries to approach me, I push them away. Some people mistaken me for have autism or aspergers sometimes because I don't talk to people. Sometimes, I think death would make me happier than being alive, although I don't plan on committing suicide or harming myself. Sometimes, whenever I'm in a happy setting, like a party for example, I just start crying for no reason. I started to hate everyone for looking more cheerful and happier than me. The only people I don't really hate are my parents because, I mean, they have done many things for me so I have to appreciate them. I kind of started to disconnect from the world around me. I've started to fantasize a world where I can be whatever I want to be. The only thing I live for is to get a job eventually so I can have money to support my health and continue to fantasize about the world that I will never be in. The only thing that makes me happy in the real world is watching anime alone in my room. I have become more careless about taking care of myself too. I've started binging on junk food and stopped exercising.

My father was also in denial when the psychologist said that I might have depression and said that I was just going through a phase and this happens to lots of teenagers. I'm 14, by the way. I know it sounds like I'm just being emo/depressed wannabe, but I'd appreciate it if some of you could take it seriously and not say how I'm some emo teenager who wants attention.
