What can someone do when a diastasis is causing all types of medical problems; pain, addiction to pills, depression~will insurance cover the repair?! Medically necessary!

Good Evening Everyone!

I have been desperately searching the web for some hope regarding my diastsis and the associated problems from it. I had back surgery in 2006 after having my son in 2005. I look like I am between 6 and 8 months pregnant and there is a physically visible and unquestionable separation of the abdominal muscles. I have digestive problems and have been on COPIOUS amounts of dangerous painkillers so that I can work (against doctor's recommendations) through the pain. I feel that my only chance to lose this hanging weight and lack of strength around my middle and get off these pills is to have this surgery. However, I cannot afford to pay for plastic surgery. What are the chances my insurance will pay? I have had a c-section and back surgery (lumbar area) and there is ZERO muscle tone to hold anything in. I have been put on anti depressants because of all of this and the meds I take (aside from their dangerous nature just because of what they are) cost my insurance between $1,000 and $1200 per month as it is. Any advice at all will be so appreciated as I have been depressed and in pain just thinking I was fat and deformed until I read about the diastasis. Now I feel there is hope, IF I can get my insurance to cover it...I am going to post most of this online as well in the hopes that more people can offer me guidance. Thanks again for your time, take care!
I want to get my life back; end the pain, get off these dangerous meds, and feel good about myself again. Maybe stop being depressed too...?!
