Hi A&A,
Not sure how to answer that except to say that 'no', you are not completely alone. You have this forum, and everyone here has experienced the exact same fear you are feeling. Whether it is the PALS or the CALS, we are all in the same boat. It does get better, in time. Once you get a diagnosis, one way or the other, you begin to make any necessary adjustments. Life is not yet over, and it can actually take on a whole new meaning, believe it or not.
Also, just a tip, it's easier to follow the conversation if you reply on that person's profile page.
Jump on the forums any time with your questions and concerns. Try to pick the 'thread' that is most relevant to your thoughts, or you can make a new one if you don't see your topic. If you post in the right places, you will get more responses.
Hang tough,
Steve
