Hi my son has told me tonight that he thinks about hurting himself. He said he hasn't acted on it but just wants to make the pain stop by being in pain.

I am way out of my depth here and don't know what to think. He says he has felt like this for about a year now. I put his quiet and reluctance to talk down to teenage years (15 in August) but then this.

I feel glad that he has at least told me and have booked an appointment with gp but then I remembered reading in side effects of montelukast and checked and it can be. Does anyone else have experience of this or is it just wishful thinking that at least there is a reason iyswim?
