My 17 year old daughter has recently begun the process of officially being diagnosed with autism (what was initially called aspergers). Since she was initially told she was on the spectrum her behaviour has severely deteriorated to the point where she refuses to spend time in the same house as her younger sibling, refuses to help around the house, won't get out of bed and today she has ruined christmas by refusing to spend time with us and spent the whole time in her bedroom. She seems to have a particular problem with me, her mum, and can't talk to me in a civil manner and seems to take everything i say as an insult. I understand she has issues that stem from her autism and have been the parent who has fought to get her diagnosed and getting her help with her mental health issues but just seem at a loss on how to deal with her anymore as i can't tell what is the autism and what is just normal teenage behaviour. We just seem to be at loggerheads all the time and i am frightened i am losing her because i am not dealing with things as i should and i just feel lost and alone and at my wits end.
