Jason Williams family fund

My husband, Jason Williams passed away in a car accident on October 7th of 2013. He left behind myself and three children. Our daughter is 18 and is living out of our home. Our sons are 14 and 5.
Jason was a 12 year naval veteran and had spent 10 years in law enforcement. At the time of his passing he was a full time student using the post 9/11 GI Bill and was 2 months from graduating at the top of his class. For the first time in our 15 year marriage we had no life insurance. Our sons and I are surviving, but I want so badly to make their lives better and to do more than just survive. I just need to get our feet under us and I can't seem to do it on my own.
