I have to face a lot of changes im not ready for

I've been sick for over a year and its been bad but with occasionally tolerable moments. When I was working on getting the right doctors I lost my health insurance and haven't been able to recover it and from that point on I became more shut-in. Having my health issues get worse and to points where I cant get up and move around, my anxiety and fear became a big problem. I was doing really bad one day and had to leave the house after not leaving for months and I had a panic attack and after that I was slowly trying to get used to going out despite my bodies problems. Now I have to move to another state and the drive is 18 hours roughly and I dont kmow what to do or how to prepare for it. I dont have time to slowly adjust myself and I dont have medication to help treat any of my health issues. Everyone says just push yourself and that its not hard but why cant they understand how much im already pushing myself and how my body can crash or i can enter a flare or whatever else. I'm scared tbh and am looking for support from people who could understand my predicament.
