I Am Due For An Adderall Refill And My Family

I am due for an Adderall refill and my family doctor decided she is no longer going to refill them for me & that I need to find a psychiatrist to get my meds from now on. I have been unable to find a psych in my area and it's now been over a week without my meds. I can't take much more of this- I am a mess without it and I've been on it for 8 years! My question is- why did she do this to me without warning and where can I get it filled?
