New diagnosis 18 year old daughter

Hi,

My daughter has struggled since late primary school and during her secondary school years went downhill with anxiety and depression and self harming. Through cAMHs finally just prior to her 18th birthday she was diagnosed with ASD. She is on Fluoxetine for anxiety and depression and this seems to have improved her mood. 

She is high functioning and loves her gaming PC. Since her diagnosis she has changed a lot. I’m wondering if this is a release because she now knows why she has been struggling for years and years. For me, I feel like she is a different girl. This is a good thing but since diagnosis it’s like I don’t know her anymore. Has anyone else experienced this? 


I’d just welcome advice on how to deal with a diagnosis. As a mum I feel lost and worry about her every day. I don’t sleep anymore as she used to run from the house although this has settled down recently. Also, she’s hoping to go to Uni and I worry how she will cope. 
Thanks for any support, advice in advance.
