What do I do?

I'm almost thirty weeks. Me and my fiance wanted to get pregnant and accomplished our goal. I also have a three year old which Derrick took on without hesitation and started raising as his own. September 16th mt fiance was killed in a motorcycle accident. It has been the most horrific and sad 9 weeks of my life. My son asks constantly about daddy, wanting to call and talk to him, but he is to young to explain that's daddyn isn't coming back. Some days Idk what to do or how to carry myself. Guess I just need a friend or idk really. Just know that I'm ready for this sweet baby boy to get here. Its going to be extremely hard to bring him into the world without daddy beaming beside me with pride but I'm ready to look into his face and see his daddy. I miss him terribly. But I thank god everyday that my children and I have the best gaurdian we could ever ask for!!!!!!
