I need advice. My 15 yo boy is lovely 90% of the time. But once in a while he goes off on one big time- swearing, punching doors so they break, screaming, being very intimidating tbh. We left an emotionally and sometimes physically abusive man a few years ago and clearly there’s fall out. I wondered if anyone could advise on how to deal with immediate situation (it’s happening now though he’s gone quiet for now)? I am going to call Cahms for emergency advice in morning but previous experience suggests he won’t participate. Desperate for advice please.
