Sorry that I got caught up in my own grief last night when responding to your questions. I hope I helped rather than depressed you even more. I also didn't mean to imply that it was fun in any way, I just hoped that you would see that I tried to make the most of the situation.
I believe that God has a plan for each of us and that in taking care of my mom, I was supposed to learn some things for my own life. I'm not sure that I learned the right things, but I know I learned lots of lessons and appreciated the time we had together. I loved her much more as a result of my caregiving.
I'll pray for you and all caregivers and please feel free to PM anytime if you think I can help you deal with the frustrations and heartache.
