My dad is ill help me and boys

Hi my name is Anastasia this is my story. I havent seen my father in 6 years. In that time Ive had to sons who havent met there grandfather. Just last year he had alot of health scares. Well today i got the worst call possible. He told me that he has cancer. They dont know the stage or how bad it is of yet. If you know me im am a daddys girl through and through. Im asking for help to go and visit him and see my dad and so my sons and husband can meet him. I dont have any extra money due to the fact of bills and taking care of my children. It would mean a great deal to me if i could go and see him. If anybody can help it will be greatly appreciated. Even if its just a share. To get my story out there. He was supose to come and see us on the 18th of this month but his health took a turn for the worst. So i ask please help me go vist my daddy. Thank you in advance to everyone
