Struggling with a Hip Injury

Hey beautiful people, I'm having a really hard time mentally and physically. In March I was working out and something popped in my hip and it's been in horrible pain since then. I've been to doctors and they haven't got a clue just suggested physical therapy and that was too painful at the time. I went to an orthopedic hip specialist and had an MRI on my hip and lower back and nothing showed. I've been really pushing myself since nothing seems to be wrong with it but I just keep over doing it and ending up in bed from the pain. Sitting up for long periods of time, standing, and walking a long distance really aggravate it then it's just more in bed resting. I'm getting a second opinion with another specialist and pushing through the pain with physical therapy. At this point it has been months and I'm so done with this injury that I just want to give up.
