I suggest you make a list of things you'd enjoy doing this summer. Do you have an interest you want to persue?
I have many interests and they have led me to get out of myself, meet and share with others and be happy discovering many fascinating areas of life.
All the preoccupation and worry for another does not change a thing.
Do what you love and enjoy....follow your dreams.
I learned to discuss problems related to AS and myself with Alanon members and some family, perhaps a friend or two as long I and they were comfortable.
Life is not just our troubles, it's a fabulous rainbow of discovery.
