Same!
Tbh I never get my hopes up with cup competitions, it's all about making sure you give it a good go.
Let's be honest - A club like Fulham for example will never go into the FA cup expecting to win it, sure they'll get upset when they get knocked out but most of the time clubs like this will be happy with a giant killing or two.
Some people get their hopes up too high - the game becomes so much more fun if you don't set stupid targets and just take it game by game.
For example - I just started a new team this season, buying no tokens as opposed to my main team which gets heavily invested in, and I enjoy managing it so much more because I don't have any expectations, I take it game by game and it feels much more real!
To be honest, I think the problem lies with how easy it is to win the League and Champions League competitions when you have invested a little in the game, I practically expect nothing less than 1st in each with my token buying team, so the only thing I have left is the Cup which is so elusive - sometimes it feels like the only competition left in the game worth challenging for, so that's why the emotions run high when you get knocked out of it season after season.
