Hi Tammy @jtmarsh and welcome to this site,
I feel your emotions and the negatives of Type
one has overpowered you - there are many people who have improved their characters because of their diagnosis with diabetes - try looking on the positive side. Actually it appears that TypeOne has lengthened my lifespan - more than half my high school graduating class has died - and my life was and continues to be very productive. I was diagnosed on my 16th birthday.
As for his potential MLB career, there are several current players in the majors who have TypeOne Diabetes - watch a few games and notice pumps - including an All-Star pitcher who was one of the speakers at our JDRF Summit last December. Certainly your son lost weight - in the weeks before my diagnosis my six-foot frame fell to 124 pounds.
