Pain as always......

I have had severe pelvic pain for 3 1/2 yrs now. Every since I had an emergency c- section with my daughter. I am 24 yrs old and feel 80. My symptons are shooting pain in my pelvic are that goes down my legs, severe pain with intercourse, when its cold out side, during my menstrual, when I try to sleep, when active such as working etc, stressed, during a bowel movement, pain when I urinate (before and after), pain worsens at night. I have had so many MRI's, ultra sounds, x-rays, pap test.3 1/2 half yrs later they found my uterus is enlarged, I have a complex cyst with internal echoes with in the left ovary, small follicles in the right ovary, trace amount of fluids in my cul-de-sac, thick endometrial stripe. What s this and whats it caused from. (Bad labor) or is even my pain? I have heard I could have Fibromyalgia, irritable bowel syndrome, Endometriosis etc. I can never get a real answer and it seems like I just keep getting passed from one doc to another. I have been taking up to 12 tylonel a day for 3 1/2 yrs and I am so tired depressed, weak and stress over this. I have a beautiful little girl that needs me and I am lost I really have no more places to go! Can someone help me?...... If I do not die from whats wrong with me I will with liver failure, kidney failure. I am so lost.....
