Feeling so burnt, any tips on how to make time off school easier for my child

My little one is really struggling with her change in routine with it being the summer holidays. Every day is so difficult , not really content with anything, constant meltdowns & I just feel so burnt out. I’m trying so hard to keep her busy, giving her activities to do, loads of baking, new puzzles & toys , days out & it just feels like it’s never ending screaming. I feel so horrible for wishing she was back at school just for a few hours of peace. Every other year she’s been glad to get off because she was in a mainstream school but now she’s in a Sen school & has gotten on soo AMAZING this year, she loves her teachers , her wee friends and is so happy going every morning & that’s obviously why it’s such a struggle. Any tips for things to help, she’s 5 years old enjoys puzzles, music, baking, and just running around outside in general. I’ll take any ideas if anyone has any advice, just feel a bit lost no one around me has a child with autism so can’t get any tips from anyone
