Hello, I just want to start out by saying I'm not sure I'm depressed. I'm only a teen (im a girl). It started about 5 weeks ago when I started getting these really angry episodes. I would get so mad I would lock myself in the bathroom for a long time until I stopped crying. They got better so I though I was fine, until this past week and a half. I started feeling really uninterested in everything. I'm homeschooled so I used to be a straight A student in everything, now in get Bs and Cs in my best subject. I used to want to finish my school really early so I could watch my favorite TV shows and now I'm so uninterested and bored from them. I'm restless but lazy all day and almost never leave my room. I get so bored I'll just feel empty and sad. I have recently been self-harming. I only cut across my fingers but I want to do it a lot more now. I don't have any friends I can talk to about this either. Being homeschooled I only know 1 friend who lives like 2 hours away now, that I never get to see. My social life is 0. Being uninterested in my school has made it really hard for my mom, we argue everyday about it and it makes me feel very stressed. Whenever I leave my room my family says "oh she leaves her dungeon!" They really don't know how much it hurts when they say that, it makes me feel horrible and crawl right back into the 'dungeon'.
But I'm not sure I'm depressed. Am I just making myself worse by knowing the symptoms now? I've been reading a lot about depression. It's mostly categorized by sadness and having the symptoms for months. I've only known about this for 2 weeks. Am I just trying to put myself as depressed? I'm also happy! I have days where I may feel sad and uninterested at times, but happy when I go out and do things. I see people I could call acquaintances and I have fun.

If you read this whole long paragraph THANKS SO MUCH! I really need to know if this is real. Can you tell me?
