It sounds like you don’t really support a team but just enjoy watching football. Honestly, if you just want some crazy emotions etc. find a team that scores and concedes a lot, don’t worry about their league position or anything like that at first, that will come naturally. While watching those games you’ll get to experience multiple emotions throughout the match.

Also, maybe just don’t watch football then. When I stopped enjoying going to the cinema, I just stopped going. Watching isn’t an obligation.
