I know I cannot banish my anxiety about somethings, but I can assure myself that simply fretting will Not help. So I do try each day ways as to How I could manage my anxiety well. After giving enough attention and coming up some ways to address it -- finding new ways to seek friends whom I may find helpful to assuage my worry for a future without friends -- is what helps me move on from worrying, realizing this is just a wasted now but will also diminish my efforts to find friends later on or next day.
So I am able to sleep well each day...and wake up with the first thought as to how make my day most useful toward my goal. Tomorrow I'll call a literacy society looking for those who could help school kids to new comers as old adults and also attend senior social at a library.

P.S. I found great suggestions from Ginger Volunteer Mentor in Can Anxiety Kill group above.
