The only time I ever get to myself is when my child goes to her dads and even then the time is spent doing housework and catching up with chores undone throughout the week.
I often feel guilty for wishing I had some ME time as that means my child wouldn't be with me and it would feel like i am sending her away.
There used to be a time when we could get away for wee weekend breaks and my child loved them and that was my time also, as just getting away from the "home" space meant I didn't have to think about life just for 2 days. These are no longer affordable as I just bounce from month to month wages leaving no savings behind and that's without buying any oil heating.
