I feel your pain. Same situation except raised 4 children after being abandoned. My advice is to totally create your own life and "fit" them in...trust and believe children these days often mimic their parents, the same little ones you are fretting over will grow up and act exactly like their parents, so sorry for you as I personally know how painful this is for you. Start creating your own activities and friends to keep you busy, learn how to be content being alone any time of the year. If you do that they'll appreciate you much more and don't be afraid to tell your adult child how you feel, what can it hurt, too often we suffer in silence and no one cares but yourself, learn to fall in love...with yourself!
