Why won't Egypt do more in Libya?

I'm an egyptian-american and i've always had a lot of pride in being egyptian. egypt, to me, always symbolized the pinnacle of strength and leadership in the arab world. My only question is y won't egypt do more in Libya? Now, in asking this question perhaps i'm being a bit naive, but I've tried to do some research but the focus in most of the media hasn't exactly been what egypt's role in this crisis is. Also since i don't live in egypt i've found it harder to really understand the detail about what's going on over there. Ultimately, my question is to any egyptians who might know more than i do. I understand that egypt is busy with reformation of their own government, its just that it kills me to see on the news everyday the different atrocities that go on under ghadafi's rule. Perhaps it's the pride in my heritage that wants me to see egypt come to the rescue of the libyan people, and i'm sure that the egyptians have a legitimate reason for not invading. I just want to know what that reason is, is there one besides them quite frankly just being busy with their own country?
