I personally find that trying to be kind to yourself helps,
hot chocolate if you like it or something sweet..
some candles..
uplifting music or music that doesn't bring you down..
and if you have noone to give you a hug, just give yourself a hug.

Animals can really help too.. visit someone who has a pet you can interact with..
I have a cat, she is amazing.
Hope you get your doc appointment soon x
