By Myself? Am i an A**hole?

Is it rude to walk down the isle by myself? I never really had a father figure growing up .I really dont think my dad can make it to my wedding due to him having alot of health and financial issues. So his appearance might make everyone else feel uncomfortable and i dont want to have to worry about him being made fun of. I mean i dont have the best relationship with him anyway but i just care about him.. My mom suggested my brother but ehh. I feel like i should just do it by myself and let it be my moment. So.... am i an A**hole? ha
