HI SUE,
i think you are over stressed, and your mind is going a thousand miles an hour and that is why you are falling. we have to think of every step we take, unlike the 'normal' folk, and so when your mind is racing with so many problems, it is no wonder you are falling.
try to slow down to a normal pace, really focus on that. whatever needs to be done, you will get done all in good time. try to just think positively of the days to come, and that you will be in your own place, and at peace. sometimes, life does not give us peace and we have to make it in our own souls. take some deep breaths throughout the day and think of how you are trying your best. do something you like or something just for you. make a few good moments for yourself each day. you deserve it so much.
take care of the foot .... you are special so be kind to yourself.
love, joan
