Hi Blue, I didn't think I would meet you here.
If you have a look at my blog (the link is at the bottom of the post), I have written on that subject several times.
If you need to know any more PM me.

hi blue,

i may be able to give you a few tips as this is what i've done in my life.
i don't think that much into the future. i try to take things one day at a time.

worry just makes you give up your personal power. it drains you and doesn't really change anything. now planning ahead is a better way to think about things.

i have MS and i got dx'd with breast CA last yr. i did what i had to do tx wise but when it was over i considered myself cured. i don't worry. i may think about CA but i have a mental plan if anything happens.

i hope this makes sense. for instance i live alone. i'm not afraid. if i needed to i could get one of those button devices for emergency aid. so, having a plan buts my mind at ease.

it also may help you to journal, even get some counseling to help with your worries and thoughts.

hope this helps a bit. when you make a plan of action you get your power back.
