Chronic pain

I’ve been trying various medications for depression over my almost 20 years since diagnosis and had been settled on generic Pristiq and low dose generic Abilify, my brain seemed to like that combination. Six months ago I was diagnosed with CRPS, and in that time the pain has become progressively harder to treat and manage, so one provider suggested I consult my psychiatrist about switching over to duloxetine. I’ve recently cross tapered and have fully transitioned over to the new medication and after a high pain weekend my mood is so low. My medications specifically for pain do not treat that well, I hurt in areas of my left arm and shoulder almost constantly with little relief. I’m trying to hold on until my next appointment on Thursday because no guarantee this doctor will even want to help me either. Does anyone else struggle with depression and moderate to severe chronic pain?
