I know zara has posted about it last year but here we can discuss our experiences of christmas and our tips and tricks to cope. especially as i'm an undiagnosed autistic with probably tourettes.
I would say its harder if you're with extended family who don't embrace or understand your conditions. or if the family members have different traditions your not used to or know about.
fortunately we normally have our immediate family and our normally at our house with our traditions. If we see other family its either later in the day or at another time.
Ik its a while till christmas but my tips are:
Explain to your family and ask to make it as small as possible
You dont HAVE to open gugts infrint of people and you can always text them later to acknowledge it!
