1. Go to the doctor (there or here, just go),
2. Get a very thorough exam,
3. Spend lots of money on lots of tests and get:
a. Peace of mind,
b. a di ag no sis of ALS, or
c. a di ag no sis of something else that is treatable.
4. Save up for a new laptop.
5. Purchase new laptop.
There you go. Plan of action, itemized in order of importance, and easy to follow. Have a great life! And if you get (b.), come back and see us.
