How to get through the holidays?

Megan • Happily married. One 2015 angel baby, little girl born Sept 2016, & one due June 2019.
I'm feeling very down and withdrawn. I miscarried in August at 8 1/2 weeks. We put a hold on TTC until January when this past cycle didn't work out. If it we would have gotten pregnant we were going to tell our parents today and family and Christmas. It's just so frustrating. We've been TTC for nearly 3 years. I still feel so empty since the MC and I'm not sure how to get through the holidays.
