At wits end now. DD is almost 18 and in upper sixth doing 3 A levels. Has been smoking week for a year now. We have tolerated it but have a rule that we don’t want her smoking it in the house, which she abides by. She smokes it with friends. The problem is her mental state. She seems disinterested in her college work and had a poor report recently. She is very bright and had been doing very well. She has suffered on and off with depression since she was 14, and still does. Now we wonder if the weed is fuelling her depression as she is often really down. She has difficultly sleeping at night and then goes to sleep after college. We have talked to her about the long term mental impacts of weed, but she insists it is helping her understand her feelings and helping her open up, as she tends to bottle things up. Me and DP have both smoked it in the past, but never regularly. She was seeing a counsellor at college since September but that has finished now. We are so worried about where she will end up. Please help!
