I get excited when the Blades win and feel disappointed when they lose - but I can honestly say I've never got "angry" about it. I think that's very negative if it's doing that to you?
I suppose it depends on how much your life revolves around Sheffield United?
I think Sheffield United are a big part of my life, I've been watching them for nearly 50 years and I go to every home game and maybe half the away games every season. However, it's not the be all and end all in my world.
I can see how for some folks it is though. I just think if it's getting to you like that you maybe need to find some other outlets for your thoughts and energies, otherwise it will consume you. And believe it or not, there's more important things in life than letting a football team control your mood.
