Why am I suddenly breaking out?!?

I've had great skin my entire life . Throughout my teenage years , I had the occasional pimple or blackhead but nothing major . A little over a year I started getting a lot of white heads and large painful pimples . I proactively for a while and my skin improved , then much , much worse . Proctive I left at the end of last summer and in the past 3 months I have beaten their lowest point . Now I have cystic acne ! They usually have at least a small cyst and several " normal" pimples . Cysts are absolutely horrible and badly wounded . Last winter I had one on my forehead that came and went pretty quickly and was not too noticeable , but then only had regular grains . It was more of a red bump , these are large, flat, white on top . Very , very remarkable . I've actually picked up and people looking at them! I do not get that. Why am I suddenly burst into the ge of 21 ? ? MedlinePlus The only things that are different from my life now before my teenage years are : MedlinePlus 1. I've been sober for 15 months. Meth and ritalin was my drug of choice , along with alcohol and marijuana . MedlinePlus 2. Only recently ( bout 2 weeks ago ) stopped receiving my chance deprovera . MedlinePlus I know I should see a dermatologist , and if I had good insurance or the money would. Im saving but until you can afford it , does anyone have any answers? MedlinePlus I'm desperate . I feel so bad every time I look in the mirror . I hate my face ) :
