Frustrating to get meds, any tips

I started vyvanse last month. I paid 433 dollars for my first month of name brand as I had NO insurance at the time and things were so bad I bit the bullet to hope it would help get my life together. It really helped immensely. I lost weight healthily got alot done and my life structured, so when i went to get my first refill yesterday now with insurance I was expecting a decent change in cost. We'll I was right but in the worst way. No generic was available of course (we love big pharma!!!!) And the name brand was 440 dollars AFTER my insurance covered 100 dollars. You mean to tell me that name brand went up 100 dollars in a MONTH? I can't afford that, and I cant find generic anywhere. Not sure what to do I've called 30 places atp. This sucks man
