Feeling so burnt out

My little one is really struggling with her change in routine with it being the summer holidays. Every day is so difficult & 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, 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 & that’s obviously why it’s such a struggle. Any tips for things to help, she’s 5 years old enjoys puzzles, 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
