Sorry to hear about your heartache, and yes it truly can sometimes be a heartache when your child chooses to create a rather significant inconvenience to Mom than to postpone a nap time for your granddaughter, to pick you up at the airport, that is very thoughtless in my opinion. Have you tried sending her an email? Sometimes when you send your kids something in writing it resonates with them more and they think twice about how they're treating Mom lately. Things have to be spelled out clearly for some kids. I remember when my husband and I had to move from one state to the other because of health issues (no family close by and kids wanted us to move closer to SOMEONE! we have seven kids and most wanted us to live near them, one in London, one in Canada so that was out of the question). I was exhausted with stress at the time as my husband was in the hospital in the middle of packing, he's 84, I'm 83, and I called my eldest and really sounded off to her because of all the stress involved and next day one of my sons drove down from San Francisco and did the lion's share of the work..so it does pay off when you let your kids know exactly how you feel(in this case via another kid) and what you expect..at least in my case it did. What's the worst thing that could happen if you open up to them by either calling or writing? You sound completely overwhelmed and if you've been shouldering your burden by yourself all these years because you didn't want to add to their load, then it's time to clearly let them know you need them now. Good luck!
