I am worried about your trying to do too much when you have these multiple health challenges. Can you get help through the Canada Health system? Allergy care? Vision care? Dental care? Is there a social worker that you can hook up with? Starting a demanding series of classes, taking on substantial debt and doing other self-imposed projects while your body is begging for rest and repair might be doing too much. Can you take care of your health, earn just enough money, and maybe take one class a quarter to get into the swing of it? It doesn't pay to drive your body past what it can do at the present time.....mg
