Grieving the lost of 5yr old baby boy

Melissa • 37, FL Mother of 3 (👧🏻👦🏼👼🏻), rest in peace my sweet baby boy 8/3/17-11/24/22 💔

My son recently passed in a tragic accident on Thanksgiving day, he was 5 yrs old and non verbal autistic, I am devastated and am overwhelmed with guilt, pain, I have no closure I don’t think I can ever heal from this unbearable pain.

Anyone have some tips on how to cope, I am at a dead end.. I don’t know what to do..
