On the fence about spending Christmas alone. Need convincing!

From the UK. Dad lives in Italy, mum and stepdad live in wales and have been invited to either or again this year for Christmas but I keep ruminating about the idea of doing it along this year. I like the idea of it but I don’t know if it’s just because of familiarity.

Family or not, I feel very restless and restricted when I have little bouts of anxiety in different places and I rely so heavily on certain routines and behaviours when I feel this way (never anybody’s fault, it’s usually just a sensory thing or being not familiar enough with places) and I really need to be in (or close) to my flat for those moments.

Anybody else turn down invitations for similar reasons and is anybody else spending it alone? Please convince me that it will be fun!
