In past years I've had a history of self harm and cutting.

It reaches from my upper and lower arms to my ankles. Anyways I'm almost sixteen and I have come to know that when I turn 16 I have to get shots. I hate shots in themselves but the place they have to do it is where I have must my scars. And those scars are still pink. I'm scared that when I have to get it done they will inform my parents. My mom knows about them but hasn't seen them because I wouldn't let her see them. I said I will show her when I'm ready. But it's still 4 months away but the anxiety I get from it effects me so much it almost hurts. I just need to know what to do or something that will put me more at ease about it because I'm so scared for mom mom to find out all over again....
