Maid of honor

Not sure why I’m posting this on this page but I was hoping someone could give me advice. I’m getting married and I have tons of friends that I want to be my brides maids but I don’t have like a best friend to make maid of honor. All my friends are like different groups and mostly were a group of three so if I pick someone from one of the groups I’d be hurting someone’s feeling and the one person that I would most likely pick would be a terrible maid of honor honestly because she’s too selfish but we’ve been friends forever but she’s not even an option so i don’t know what to do. My fiancé is my best friend but obviously I can’t pick him lol I could pick my aunt who’s close in age with me and we hang out but not a lot so I don’t know if it would be weird to pick her but we’re family. Anyone have any advice for me? I know this is weird to post on here but all of you seem so good at giving advice so I thought I’d give it a shot.
