Wedding Without Dad

My father died 3 years ago. I am currently planning my wedding for next year and I am really struggling when I start to think about the traditional parts of the wedding that would have included him. Part of me is thinking of walking down the aisle alone and scrapping the Father/Daughter dance. Part of me is thinking of asking my uncle to do those things but I worry that having a replacement will just make me more upset on the wedding day. Looking for suggestions on what other brides have done or are thinking of doing that have to do it without dad. Thanks!
