I try very hard not to look into my future as i really don't like what i see there. One day at a time is enough for me to cope with. But sometimes it's necessary to have a big shake up to get out of the ruts we fall into so easily.
My situation will be very different to yours, but i expect we have much the same needs. When my husband became ill all real conversation between us was lost, and since he wasn't making any sense to anybody friends all dropped off too, thats when i became isolated. I was trying to exist in a world where nothing happened, nothing changed, we went nowhere and did nothing.
Something had to change. And the only person who could make those changes was me.
So I worked out exactly what i did want, i needed to be able to hold a proper sensible conversation. It doesn't sound like much to ask for does it? But i had to work hard to find a way of doing it that fitted in with my caring role.
I did find my way round it, it didn't go down to well with my husband at first, but i stuck with it and now my going out for a couple of hours one night a week is not an issue, although i do admit that when my husband is really bad i do hurry home a whole lot quicker, but thats life.
All i can suggest is that you also work out what you really want change, be specific about what your needs are, once you narrow the field down inspiration might take over and the seemingly impossible suddenly looks as if it might be possible.
All the best ena
