Since you do NOT have ALS but are, for some reason, "super anxious" that you will get it, this fear is triggering your anxiety. I would also guess that you've been Googling symptoms for ALS which is only exacerbating your anxiety.
Try to relax until you see your doctor in August, which I know will not be easy, but it appears you don't have much choice. Is there no other doctor you could see sooner?
You could still go to the ALS Forum and discuss your concerns with people who really DO have ALS. I bet they would be able to reassure you.
I dont have it im super anxious about possibly ever getting it and its all i obsess over, i need to lnow if if crazy or not i cant get an apppontment with a gp until august
I'm sorry that you have ALS. I believe you would find more information and support on our ALS Forum. The folks over there also understand anxiety and can help you with all your questions and concerns.
