How is everyone handling their insurance?

Look, the only reason I came to Walmart 3 years ago was for the health insurance. I was going through some medical issues and needed to have major surgery 6 months down the road. Had the surgery and all the tests for it and all is fine now in that regard. However fuck Sedgewick and everything they stand for. Just the absolute worst people to ever have to deal with. If my doctor forgot to dot their i's and cross their t's, it was a problem.

I'm still here 3 years later, and going through some health issues that's affecting my work. I've been to the doctor about it and they wanted me to have a CT scan and we scheduled it. Only come to find out I would need to pay the co-pay upfront, which was $2000. I make a little less than that a month full time after 3 years. There was no way. Canceled it, ignored it. But it got worse and I had to go to the ER, and they did a CT scan and found nothing. Treated me for my symptoms (upper gastro stuff), and felt better and gave me a gastro doctor reference. Paid $75 for that visit, which was almost a day's worth of work pay for me, only for them to tell me that they'll have to do a endoscopy to know more. Scheduled it to find out I would have to pay $750 upfront for that. So once again canceled.

I don't know what to do at this point. It's not serious, I've been dealing with it for like 7 months. But I need help and I can't get it. Like what the hell am I paying money out of my paycheck for? I need my meds, so in that sense it's worth it. But I just don't understand what happened and why I can't get the medical attention I need. I have no reason to stay here anymore.
