I need advice and support.. Please help.

Last Saturday morning my dad died. Next week I find out the gender of my third baby. I've a lot going on in life and have basically been by my dads side for the last six years. Now that he's gone I don't know who to ask about my car or computer or anything.. Like what do I do? What do people without parents do when they need help? I'm only 21.. I need my daddy.. I just don't have much support and I don't know what to do from this point on.

I also don't know how to respond to the people I haven't seen in over 6 years who are now popping out from everywhere saying how much they loved and cared for my dad but they weren't there the last two years when he needed help and support going through his chemo. I'm just completely lost..
