Feel like dying.

Chronic never ending Pain diagnosed almost a year ago with tendenosis not to be confused with tendinitis. I'm 23 and this is the worst pain I've ever experienced. I will take way more Ibeuprofen and Tylenol In a day than I am supposed to which does nothing. I've tried Icing, heating, stretching, massaging, various supplements. I take CBD as well as smoke Weed all day everyday. I do all this and turn to drinking where I feel little pain relief. Nothing is really helping and I fear I am killing myself. I can't sleep most nights regardless of how tired I am because of the pain. It doesn't matter if I got 4 hours of sleep and took 10 mgs of melatonin. I'm just not sure what I should do. I'm not rich and doctor suggests PT but I've looked at everything they can offer at PT and have already done it or am still doing it but only get worse. I do not work any labor intensive job in fact I'm taking care of my dying grandmother who is on hospice and she mostly sleeps so while she is sleeping all I do is rest. Any ideas on what I should do. :(
