TIRED,
It is such a perfect word for that drained feeling. God, I so know it! When I was finally TIRED of feeling out of control, feeling pain,sadness, and disapointment because someone i loved was ruining their life, ( And I believed in doing so, was ruining mine). I got tired of being tired. Tired of forgetting about my life. So I began to go to Nar-Anon and Al-anon meetings to take my life back. I still love my AS and hope and pray for him, but I am learning I only have control over myself. And fixing myself is hard enough work as it is. So I am giving my son over to God. And I am less tired. I hope you find this also. Keep coming back. Read a lot. there are good people here.
