I do not think that the scenario you stated is a live bet but rather just plain betting since a live bet is like putting a bet while the game is happening not before the game is played just like what Oshondy stated.
Honestly being a fan of a playing team, it is hard to contain one's emotions especially if we have a bet that our favorite team will win. I know it is really disappointing if the calls of the ref and the game performance of the team don't go what we expected. It is normal to be emotional during the heights of the game and it even lingers even after. I managed my emotion by simply making sure that whatever the result of the game was, I did not let it affect my next activities.
