Well today you did it. But I don't want you to do it again. This will be the last time you play victim and end up getting so angry that you start tearing up. Usually your outbursts and anger are just angry, but there was something truly hurt at your core, and I want you to fix that. But first you must identify it.
With your family, you are hurt by them. But being hurt does not give you the right to hurt. They did the best they could under the circumstances, or at least gave you all that you needed. AND, honestly, it's because they were lacking that you grew up to be as strong as you are. And I know you wouldn't want to be anything but strong. But you can't change them. You can change you. You can either be soda or water. When people shake you do you explode or do you stay the same? Stay the same, friend.
With yourself, you need to work harder. You are not working hard enough. In school, in fitness, in all arenas of life. You need to be a fighter. You need to get into that mindset. Eat well, work hard, play harder. And rest appropriately.
See you in the battlefield.
