I think I'm going to run out of seroquel

I keep on having to take more of it out of desperation. And I can't get my prn seroquel until June 2nd (something to do with my insurance. Not because I was taking too much of it. My pdoc said I could take 100mg prn daily if I needed to. It's not my fault my stupid pharmacy gave me 50mg tablets instead of 100mg!).
This is sucky

What am I going to do? I CAN'T ****ING SLEEP!!!!! I see my therapist on Tuesday. I'm going to talk to her about this situation.
