I hate sleeping at other people’s houses

Hi! I’m Samantha. I’m autistic and change makes me upset. One of the things that really makes me upset is when I have to pack up and go to someone’s house other than my sister’s camper when I stay with her every July. I actually like staying with my sister. But I don’t like staying at other people’s houses. Especially for the first time. It’s not like sleeping at my house. I need to sleep with a fan every night or else I won’t sleep. If I sleep at someone’s house then I have to bring something like zzzquil to help me sleep. Last time I was at someone’s house, I was at my sisters apartment and I couldn’t sleep. I sleep better when I’m at my house.
