I'm so fucking tired of this

I have a bad back. VA has done a MRI and my problem is clearly visible so they know I'm not faking it. They say I'm not a candidate for surgery so they have decided to treat it with pain pills. Which would be OK except they don't wanna give me what works. Oxycodone works but they only give me 20mg a day. They won't give me more of that but they'll give me morphine and now they're gonna try methadone. Oh well, I guess I should try it before I bitch but I'm getting frustrated. My quality of life has gone to shit. I barely get out of the house anymore. Ugghh.
