Sick of insurance being tied to employment

I’m chronically ill and I work in healthcare because everyone said that’s where some of the best benefits are and it’s true. If I leave I’ll probably never have a better insurance plan but I hate healthcare. It only makes me sicker, I’m tired all the time and moody. Any of my friends who are self employed don’t have health insurance and I wish I had that same privilege to choose. I don’t know what else to do
