Hi - im at my wits end. Can anyone help please? I am a single mum in Welling, Kent, United Kingdom. My 16 year old son is smoking Cannabis - but denies. He has been very bad at school - the last 2 years - which are the most important due to GCSE exams. The school didn't want him there because of him being disrespectful and rude to them so they put him on a "reduced timetable" which basically means he could study at home, so a polite word for "expelled". He however did no revision whatsoever despite my many attempts to sit with him and help him. I would just get "I will do it later or tomorrow" all the time. Now he has come out with rubbish results. He has a place in college starting on the 7th Sept doing plumbing but he hasn't been there as yet to enrol. His attitude towards college and learning is not good and he is always out and coming in either stoned or drunk at all hours of the morning. The latest thing happened this morning. He was borrowing my phone as his one was stolen at a party - (he says) and he has smashed the screen of the phone in temper. I was at work at the time but my partner found the phone on my bed and heard my son getting angry with it. He has also denied this and said he dropped it down the stairs which is untrue. His father, my ex-husband is quite supportive and had my son live with him for a few months which helped but he has got worse since moving back with me. I am starting to feel very depressed, crying a lot and thinking "why me??" because I have been a good mum over the years. He constantly asks for money and I know exactly where that goes but if I say "no" he could end up stealing from me or selling things. I have been down this road before with my 23 year old son who is better but still smokes Cannabis so not exactly a good role model. I don't want to give up on my son because I love him dearly but his disrespectfulness is despicable.
