Hi all thank you for reading my post I have a sister who is in her 40's who was diagnosed as under active thyroids at an early age. She has lived all her adult life taking tyroxine to counter this but I think she may have some other disorder?? we have another member of our family with severe autism and do wonder if she may had a form of this disorder her temper is atrocious and she does not communicate well with close family she tends to keep her emotions to her self until she has a drink which is when all hell lets loose and it dosent take a lot to get there literally two maybe three drinks she sounds slurred then when we tell her to stop we get agro then when she continues and has a few too much then ensues the panic attacks the verbal abuse and the physical attacks but it is not just a drink problem at least i don't think so.I have seen many people drunk before as i used to work in a pub and my sisters behaviour is not normal its border line Psychotic and im not exagerating. Every time i try to talk to her she thinks i am running her down or not being supportive but i am genuinely worried Any advice please And please don't just say stop drinking i think its deeper than that and drink just lets it out.
