Social anxiety help for my 9 year old daughter

Hi, worried Mam looking for any advice. So my 9 year old daughter (10 in September) is currently under camhs. Had her first face to face last week but had to be passed to syps because she needs deeper therapy as camhs only offer 6 sessions. Anyway she’s getting assessed for autism possibly other things too. She has phobias of pretty much everything. Worst one being her or anyone else being sick. 8 weeks ago a girl in her class in school was sick during class which lead to my daughter refusing to go to school since that day, but since then things have getting a little out of hand. She’s pretty much cried from that day, wishing she was dead, can’t cope with things anymore. Her anxiety is through the roof, she’s hardly eating and just really sad. Doesn’t want to leave the house like it’s bad. Has anyone else ever experienced anything like this before? Any advice would be great. Thanks.
