College Children

I have recently lost my husband. One child is a Jr. at ucf and the other a Sr. at high school.
My husband took care of all the tuitions and applications, etc. I am lost at what to do for my HS Sr. Please help me continue to get these two thru college. It was a dream for all of us and now I feel hopeless. Please advise me of any sites or links that can help.
Thanks
