I feel so alone 😔

It’s going to be five months since my son went to heaven. There’s not a day that I don’t think about him. I’m also pregnant again with a baby girl and ever since people found out they have been treating me like nothing happened with my son. It still hurts a lot see other babies, specially boys around the same time my baby should’ve been. People tell me I have to get over it and adapt to seeing other babies cause I’m having another baby now. That’s harsh to say cause I will never get over losing my son. And its not like my daughter will be replacing him. People that have never been in your shoes will never understand.
