One of the side effects of becoming a passionate fan is that your emotions, for better or worse, can often become entangled with the outcomes of your team’s games. Try as we might to deny it, or minimize it as “just sports”, a small part of us lives and dies with our team on the field, however far away we may be in reality.
Grief is usually a result of feeling loss. While clearly not as dire as the death of a friend or family member, having to suffer a loss with your team can certainly bring on grief.
