Struggling

My son is now a year old but 2 weeks after I found out I was pregnant with him his dad passed away. I never took the time to grieve his death I just continued to work and focus on the baby. Lately I have been having a lot of emotional breakdowns thinking about how my son will never get to know his father or have his father in his life. My son is always running around the house yelling daddy and I feel guilty that he’s not here. He won’t get to have that father/son bond
