I am afraid of my doctor's appointment tomorrow

I haven't discussed what's been going on with my health and mainly because it scares me so I've been avoiding it. Tomorrow I have a big appointment, and I am scared they are going to say I need surgery or expensive testing I will not be able to do because my insurance runs out at the end of the month. Even if I get a job quickly most have a waiting period for insurance. I know knowledge is power but what can I do with that knowledge if I can't afford it? Feels like maybe it would be better not to know. These surgeons and doctors don't give this shit away. Any ways I just wanted to get that fear weighing on me tonight off my chest. I am going to go and get the tests done I can before my insurance runs out but I'd be lying if I said I wasn't afraid and I don't really want this knowledge right now. I have too much on my plate
