First Born Daughters Wedding

I am a  veteran. I am currently on disability and unable to work. I am waiting also on my military disability to be aproved. The last time I got to be with my oldest daughter prior to last few years was when she was 4 yrs old. When my daughter turned 18 we re united through Facebook. After talking for a while she wanted to come out and see me but could not afford to at the time. A flight attendant for Delta who I transported to airport many times had learned of situation and arranged for my daughter, grand daughter, and fiancee through use of buddy passes round trip air transportation from NH to Kentucky so they could spend a week with me. While they were her I could only spend limited time with them because I was a taxi driver and had to keep working to keep up with my bills. Out of a weeks time she could see the difficult time that I am going through and I was able to only spend 2 days with them while they were here. Our birthdays are 3 days apart. A couple years later I had a better job with paid time off the 3 of them were able to pay for a trip for them to come back out and visit even though thier money was tight. Now comes  the reason I need help. She is getting married in July. Two months away. She wants me to be there to give her away. I also have a 15yr old daughter from another marriage that was happy to know she had a sister and does not get to spend time with her and is really looking forward to this. At 15 yrs old she is working and saving to also help with expenses for this important event. If you are a father, or a daughter, or a sister, you would understand just how important this really is. I  want to be there for her, not just because it is important to them, but equally as important to me, I have served my country, and communities I have lived in with pride.  But due to being on disability and unable to work I have no other way to come up with extra money needed for this trip. I have always been able to help others . Even though I do not like it I am now in the position to have to ask for help myself. Any help to make this happen is greatly appreciated. If you have a caring and understanding heart could you please help us. Thank You
