Posthumous child..

I didn’t know what topic to write this in because It’s baby and relationship stuff but I’m 18 and I’m pregnant with my first child (super early along) the dad was held at gun point and passed away roughly 2 weeks ago and I’m only 3 weeks along with the pregnancy.. I just need advice on coping because I have no idea what to do with myself.. he wasn’t a bad person and he wanted his baby to have a father so bad... I feel myself giving up but I know I can’t for my baby’s sake...
