my heart goes out to you. I am in a very similar situation only my son is seventeen and a half has been out of control using ketamin for a year. Two years sporadic before that. He has been in Hospital twice, where i found him semi conscious. he has stolen and takes it most days though denies it even when i catch him in the act. I am torn , to throw him out or not. I am also on medication due to it and last yr had a breakdown. i recently found a support group for families of drug and alchol addicts. It is time we tried to look after ourselves, as this disease of theirs will destroy us, if we dont get support. we can not stop them using, only look after ourselves. we are also someones children and deserve some peace in life.
