My DH is a recovering alcoholic and has seemed to be doing really well. He took my 15 year old son to a festival today at the other end of the country. At about 7pm he told my son he was going to the toilet and has not been heard of since. My son has Aspergers and is in the tent really scared. I cannot get there until 11 o’clock tomorrow as they have the car and I will have to get a train. On one hand I am beyond angry but also terrified as he has tried to kill himself when drunk before. I am beside myself with worry. What can I do?
