Holidays after miscarriage

My miscarriage was 2 years ago and I still grieve my loss everyday. Holidays are even harder, i spend them thinking of the milestones that would be happening and how i imagine life if i hadnt lost the baby. I broke down this Thanksgiving weekend, my angel should be a year and a half and i didnt feel thankfully for anything. We have been trying for over 4 years now and ive lost hope of naturally having a baby. I skipped christmas last year and this year will be even harder now that my younger sibling has a baby on the way. How do you get through holidays without totally falling apart?
