Man do you ever deserve a break!! And so do the other pp's who are caregivers to family. Please, please take care of yourself. And do NOT let yourself be guilted!! As a mom, the last thing I'd ever want is for either of our daughters to be using their youth taking care of dh or me.
If you weren't around, believe me, your mom and aunt would have to find a way to manage. And they would find a way.
And it's totally normal to have dreams and goals, like getting out more socially, finding a boyfriend, planning a wedding someday. Those were definitely my dreams when I was younger. You deserve the chance to pursue your dreams.
