A month is not that long really - in the meantime you can concentrate on hydration, sleep, exercise, diet, and doing as much that brings you relief from anxiety. Reading and posting here is unlikely to do that.
You already know that the hallmark of ALS is failure. All the things you report could be anything else, could be nothing and could just be your perception.
So please, take control of this month as you will never get it back. Come back, as I suggested and let us know what the doctor says after examining you and running any tests they feel are warranted. Remember not to walk in asking 'do I have ALS'. Let the doctor decide what they find clinically, and what investigations those findings indicate are the next step.
All the very best.
