Condolences and good wishes to you, man.
I can't even imagine losing my dad, but sadly the day is approaching and ready any time now. A few months ago my dad was diagnosed with malignant skin cancer thats spreading rather fast. Hes been getting more and more sick since then. My mom is badly disabled, to the point where shes unable to drive and half-blind, so without him to take care of my family, I worry about what'll become of my 12 year old brother. I've been doing my best to stay strong, and encourage my brother to do the same, and hopefully things turn out well. I wish the same to you, make sure to stay strong, and keep your head up high.
