i have to walk alone...

Hey Ladies, my Father recently passed away on 8/8/2019 (Rest in Heaven Daddy) and I have no one else close to me to walk me down the isle. Is this a thing or not? I have only been to one wedding where a bride walked down by herself and her father and step father were both there. I thought about a few of my uncles stepping in, but realistically, they are unreliable. My brother and I aren't on the best terms and does not support my relationship. It makes me sad every time I think about this part of my wedding. I am also trying to figure out some ways to honor my Dad during the ceremony or while I am walking down the isle....Alone.
