Hey Nicky!
My name is Emily, and reading your story amazed me, because my story is almost identical! I just turned 17, I'm going to be a junior next year, and I too lost all my friends, but the reason why is where it differs slightly. I also have a disease called Cystic Fibrosis, and I was sick one time and my friends found out and slowly starting tip-toeing out of my life. Then when that happened was when I hit depression. When I started seeing a therapist, they pretty much took off running in the opposite direction.
After that, I began cutting ( I know I know, it's bad!). But, on the bright side, I have been 'sober' for just about 8 months now, and even though sometimes the urge is overwhelming, I ignore it and immediately try to do something to take my mind off it. It's worked so far.
I don't like talking to my parents either. Sometimes, it just seems like they ask too many questions, or they judge you, and even though I know they love me, I just can't bear to let them know I'm not really the happy-go-lucky girl they think I am. In that way, I'm afraid to talk to them.
It's good that you're seeing a therapist; I did it twice and said I was never going back. I thought she was too nosy and asked too many questions (which I guess is her job right?)
Just hang in there Nicky!
