Spasmodic Dysphonia, I need to know what I can do?

So last year I started to notice my voice going strange, after 4 months of thinking this hoarseness in my voice would kick over one day I finally went to see a doctor who referred me to an ENT doctor who told me I was suffering from "Spasmodic Dysphonia" and I was told I should see a voice therapist. I'm 20 years old, I cannot afford to see a voice therapist, i'm barely making ends meet as it is. This is affecting my work life drastically, my social life has been affected greatly, I pretty much cannot speak to anyone without sounding like I'm choking! I just need help and advice, is there a cure for this? or any advice on what I can do about this please help. The depression is starting to sink in so I'm currently in desperation mode!!
