Ginny,
Many of us live that way throughout our lives. As soon as this happens, THEN I'll do that.
If only I didn't have to do this, THEN I could do that. Excuses, excuses, we procrastinate and sabotage ourselves along the way. You are not alone.
You're right, "today" is all we have and if we started each day with that thought in mind we'd accomplish a lot more. We wouldn't waste as much time, we wouldn't ignore phone calls, we wouldn't decline invitations. We'd want to take in everything life had to offer. I feel everything we experience is by perfect design, it all serves a purpose to help us stretch, learn and grow. I can't tell you how many times I've been touched by another member expressing the sheer gratitude they feel in doing simple things like putting on socks, walking a mile, getting in or out of their car, being able to stand long enough to cook a meal. All without pain. Activity they never gave a thought before pain took away their flexibility / mobility. THR changes them. They become grateful for the small things again. It's a life changer.
Watching a loved one slowly slip away would cause you to look at your own life, questioning the time you have left and wondering if you're living your best life. What do you need to change about yourself to become a better person for yourself and those you love. Worry is a waste of time but it's in our nature to varying degrees. If your mom's passing causes you to be more mindful of living in the present and to worry less all is not lost. Look at it as the last loving gift she gave you...it can be life changing.
Wishing you comfort and peace of mind as you move through these last precious days with your beloved mom.
Sending a warm hug your way
