Gluteal tendinopathy - endless pain - losing my mind

Has anyone else dealt with this:
I'm now up to 5 months of daily pain, the the last two weeks have been the worst. I'm totally losing my mind.
First diagnosis was L5/S1, with disc pressing on nerve. I had cortisone shots, then an epidural. Not much relief, although with time the L5/S1 pain seems to have subsided. I've been doing physical therapy for almost the entire time.
For the past two months, increasing pain in left buttock and often sharp pain in left hip area. Diagnosed with piriformis syndrome, new MRI shows gluteal tendinopathy. I got two cortisone shots for that 6 days ago.
The hip area pain just keeps getting worse. I've had to cancel many plans and limit my activities. It's very depressing and is driving me crazy. Just wondering if anyone else is dealing with this and if they have any suggestions for both physical and mental health. Thank you.
