One more mom coming on to say I’m so sorry for your loss, @Melissavy.
Be prepared for it to take longer to feel like yourself than you expect and for there to be horrible moments when the grief just washes over you or stabs you out of nowhere. It really does get better, and it happens less frequently with time, Imo you are never really ‘over it’, but it does get better, but try to put some systems in place to help you through the rough spots. Make sure that you have a proxy mom or two (one of my proxy kids has at least 3 proxy moms, who each fulfill different roles for her).
Think through what you want from this holiday season - some people like to do something completely different, others want it to be as close to ‘normal’ as possible. There is no right or wrong way- follow what feels right for you.
And also: notice how puny some challenges look now, compared to the colossal loss of your mother. You can do this, and if you can do this, really, you can do almost anything.
Sending a massive virtual hug your way.
