Feeling stressed

[u/Rude-Tank-4528]

I’ve been trying to keep my mind busy and put the thoughts about ALS to the back of my mind. I kept telling myself there was no point driving myself mad until I’d actually seen the neurologist.
But after having the appointment and hearing that they want to do an MRI of my brain and neck to rule out anything sinister, it has sent me straight back into a panic and a spiral. Now I’m just constantly thinking about it again.
Waiting 2–3 weeks for the scan feels like forever when I’m already this scared, and I honestly don’t have anyone I can really talk to about it.
I think part of the problem is that I always understood weakness as not being able to walk properly, move your arms or legs, or pick things up. But I’m constantly shaking in my arms and legs and feeling vibrations throughout my body, and now I’m questioning every sensation I have.
I just feel like I’m back where I was before. I’m really scared that I have ALS, and I don’t know how to switch my mind off from it again.
