Has anyone been prescribed accutane from a general practitioner or family doctor?

I'm a 17 year old guy with persistent, moderate acne. I've struggled with my skin for four, five years. I used to struggle with cystic acne, especially on my forehead and chin, but from constant treatment that has gone down to about one or two cysts at a time. I currently have hundreds of very small, under-the-skin bumps that aren't really noticable unless you get close up to my face and they sometimes come up as little white heads that just don't want to go away. I get some black heads around my nose, and chin, and I always have around 7 or so pimples scattered randomly on my face, jawline, or neck. My chest and back have light acne, but my face is the worst. I'm currently taking pantothen, almost no success, a liquid gell multi-vitamin, and green tea suppliments, as well as washing with salicylic acid and benzoyl peroxide- one in the morning, the other at night, with almost no success other than fewer cysts. I look terrible and it doesn't help that I suffer from bad anxiety and low self-esteem. My skin is constantly oily, and is very sensitive to most topical treatments. I've tried proactive, almost every clean and clear product you can imagine, Oxy Clinical, and antibiotic pills (doxy) to help clear my skin, but never with success. I desperately want on accutane as I don't think my mind can suffer years of more acne. I have done the research, understand the risks, and figure 3 to 6 months of very dry skin is better than years and years and years of acne torture. I'm going to see my General Practitioner in a week to ask for accutane, and I was wondering if anyone else did this and was prescribed the treatment. If so, how were your results? Did your GP know how to up the dosage or to check your blood? Did they know how long you specifically needed on the drug? Determatologists are far from where I live, so if I can get good results from my nearby family doctor I'm all for it. I know this is a lot of text, but I'm desperate for information!! Thanks!!! :)
