Need an MRI

I find myself in a bit of a situation, for the last few months a series of ever increasing symptoms have started piling up to the point it is almost certain I have a brain tumor. Since Thursday (08-20) they have started to get severe to a point where I am not able to fully function, forget where I am and doing, and nights of hoping for the sun to come up. The hospitals will not take me on verbal symptoms alone. My primary doctor fully believes that there is a tumor and put in a referral that was accepted by OSU, but the first appointment isn't until Oct. 28 and at my current rate of decline I will almost certainly not be around by then. Due to being self employed and not able to afford insurance the only way things get treated in my life is with savings or duct tape. What is needed is an MRI to present as evidence to get things moving much faster. I really don't like asking for help but have also never been so clearly faced with a situation that is this desperate and my to do list is ridiculous. Need help.
