Diagnosed with RCVS. Neurologist wouldn't give me anything for it, told me to ride it out?

(28F) Have had thunderclap migraines for the past 10 days. Spent 15hrs in A&E on Sunday night into Monday afternoon, got officially diagnosed with idiopathic RCVS. I asked for varapimil to reduce the pain but the neurologist told me they only prescribed that for people with brain bleeds. She basically told me to just wait for it to go away.

My life is basically hell now. I have an episode daily. Painkillers can't touch the pain, even morphine didn't help. I'm constantly exhausted. I can't focus because I'm terrified of the next attack. Has anyone else had this experience? Any tips? I'm at the end of rope here. I have an appointment with my GP in two weeks but I genuinely don't know if I can make it that long.
