Recent loss of a child

Hello I just recently lost my daughter on 11/14/20. She was 11 months old, her name was Luna and was in the hospital her entire life. She was born a twin her brother is still here with me at home. They were born premature at 33 weeks. Luna had multiple heart defects and had 7 heart surgeries to try to fix her tiny heart, sadly the surgeries did not help and she passed away on us. I’ve been having a hard time with this loss. Her and her brothers birthday is on December 18, it is going to be hard celebrating their first year together without her here
