Why is it so hard to pray again?

Assalamu alaikum. I'm honestly stressing out as I write this. I just can't seem to get myself to pray. I have ADHD and ME/CFS, so even basic things are tough, but the guilt is eating me up. I miss those moments of prayer and the dedication I had when I pushed through my health struggles just to stay close to Allah. But then things fell apart, and one day I simply stopped. That was months ago. Now I have so many missed prayers to make up, and the thought makes it even harder to start. I really want salah to feel like a natural part of my day again, not some heavy chore. I still feel connected to Allah, but the guilt won't leave. I tell myself I can do it, but no matter how much dhikr or dua I make, my body just won't move like it used to. I'm at a loss.
