6 months preggo and just lost my dad!

I am currently 6 months pregnant with my 1st child. My family was so excited about the arrival of my baby! My child's father currently isn't involved so my dad has been everything to me. He died unexpectedly with a heart attack and he didn't have any health issues. My heart is so so heavy and I'm trying to do everything I can to avoid stressing myself for the sake of my child but I can't imagine my life without my dad. He was my everything and I feel like I can't even mourn how I need to so that I won't stress my baby. I feel like the rest of my pregnancy is ruined because I don't have my biggest supporter anymore. 😢😢😢
