You're welcome, CA. As someone who had zero time with my mom 'cause she couldn't be bothered to stick around a raise me, I can sure relate to your disappointment in not having more time with your mom. Every moment is precious and unrecoverable. Cry for her, CA. At least she gave you the chance to know and love her, and for that alone, she deserves your tears.
But don't forget that the one thing that never dies is love. She'll be waiting for you in the fullness of time.
Yes she will!
