Gallbladder Surgery

I want to start by saying that I really hate asking for help like this, but I'm in dire straights! Several months ago I started having severe, debilitating abdominal pain. If I had health insurance I would have gone to the ER, but that wasn't an option so each time it occurred I just had to grit my teeth and wait for the pain to subside. I finally went to urgent care and long story short I have gallstones. Over the past few months the abdominal pain continues along with many other symptoms. Unfortunately,  I don't have health insurance and the cash price for the surgery is over $7,000, I'm living in pain and not able to work like I need to because of it.  I have looked into getting coverage through the exchange (ACA) and literally NONE of the surgeons or out patient facilities in AZ take ANY of the plans and NONE of the plans cover out of network for an out patient surgery! I've looked into getting a plan that's not on the exchange and NONE of them will cover this, because it is a pre-existing condition. I can get insurance through my husband's work, but the premium is over $700 a month, which we simply do not have.   I've asked the doctors and surgery centers if they will do a payment plan, but they say "no" because they've been burned too many times.  My doctor says I need to get this taken care of ASAP.  So out of desperation, I'm asking for help! It's taking a lot for me to do this...I'm really not comfortable with it, but at this point I don't know what else to do. I TRULY appreciate any donation that will help me reach my goal and getting on the road to feeling better!
