I'm now faced with the fact that my son is probably a lost cause. I'm never giving up on hoping, but that hope is fragile and hanging by a thread. I'm pretty certain we'll never have a meaningful, loving, mutually caring adult relationship and that's a hard possibility to face. As for his bipolar disorder and drug addiction, I can only pray he will eventually get clean for good and learn the coping skills and mechanisms to have a life of some stability. What's really hurting is that this is my only child. I will never have another one. It's leaving a hole in my heart that not even my husband can fill. Those of you with other non-troubled children, does having them in your life make it easier to cope with the stress and heartache? Obviously nothing will completely take away your hurt and sorrow and worry, but does it help having other children with whom you have a more "normal" relationship?
