I too have several chronic physical issues.
Character defects? Absolutely not.
I have not worked with a sponsor since I finished
my formal Steps....about 18 years ago.
I don't feel the necessity to discuss AA with my medical doctors
I don't see the purpose of discussing my med's or treatment plan
with my AA group.
Sorry to know of your situation
Prayers for peace and clarity.
Welcome to SR.....
Blessings to you and your son
