That's so hard. We recently went through something similar when my parents moved 700+ miles away. My husband and I actually relocated to be close to my parents, so we saw my parents several times a week. Then, my dad was transferred due to his job, and off they went. In the past year we have seen them only a couple of times (and then only because of a death in the family and a wedding in the family). It has been really hard for us! A couple of things I can suggest:
1) Get Skype for your computer if you don't already have it. Make sure your brother gets it, too. It is FREE and allows you to video chat. Not as good as being there, but better than just having the phone and email.
2) Get a family account on Shutterfly or a similar service. Post all of your family snapshots there.
3) Plan family vacations. In your case, since you can't fly a long distance, see if your brother (and cousins?) will come to you. Maybe they would like to vacation on the East Coast somewhere within driving distance of your home. You could do camping, or meet at a family resort, etc - whatever your family's budget allows.
That is what we've done so far. It's not the same as having family nearby, but at least we are blessed to live in a day and age where we have technology that brings us closer together, and mass transit of various types that can bring us closer faster. It is more work, but you can still stay in touch! Sorry you're going through this. =(
