Depression doesn't have to happen for a reason. It often doesn't. Sure, for some, there are triggers and they have episodes of depression. but that is not the case for all. This is different than the blues. The blues is when you have days of melancholy. Depression is diagnosed after a minimum of 2 weeks straight of symptoms (like feeling hopeless, not being interested in things you usually like, etc.). Cutting is a high level of issue that is dangerous. Do not cut. What about a school counselor? What about something like a job or busy activity to keep you occupied? And your mom would really say 'what are you depressed about, people in Africa have reason to be depressed, you don't?"?? I hope not. But there are a lot of people that don't understand depression. And it scares a mom and they want it to just not be the case so she may just want to snap you out of it. You could approach it by saying "I want to be my best self and I think a therapist would help." You can try breathing exercises, meditation, exercise (which releases our body's happy chemicals), books you can get online (they have anxiety work books and depression work books for teenagers on amazon and ebay or check your local library). STaying connected is one of the most helpful things as feelings of isolation compounds the problem. Anyway, let me know how you are doing!
