Do you go to church? If not start going, you will make friends easily there, asked to be prayed apon as you feel lonely.
You are never alone, God is with you always.

You've got this Diane. Concentrate on eating lots of meat & eggs. Cut out all the junk completely.
My son was diagnosed type 1 a couple of years ago, he's 24. It's gets much more complicated for type 1 but I can advise the above. Skimmed milk, no pasta, no rice, no cakes or pastry, no bread.
All the best.
