Anna: You which Youtuber I love? Cassey Ho. You should try her workouts and she even plans which videos you should follow everyday for that certain month. The thing I learned from her is that exercise will never be enough. To completely be healthy, you have to eat right. If you're going to do an hour's worth of exercise and still finish a bucket of KFC for dinner, it ain't gonna work. As for motivation, you just have to focus. You cannot give yourself any exceptions on skipping exercise or eating unhealthy. Make yourself feel guilty that you ate that extra piece of chicken for lunch. Of course, don't push it too far that you'll stop eating eventually. The goal isn't only to get those clothes to fit again. Once you start the healthy lifestyle, you shouldn't go back on your word. Lifestyle. It's for life, dude.
"My parents were pretty trusting of me till one day I came home drunk af. I know I shouldn't have done that but it happened and now they don't trust me anymore. How do I convince them that it was only a one time thing and it will never ever EVER happen again?"
Anna: You cant. You really can't assure them that you'll never do it again because even you don't know that you'll never do it again. I say give it some time. During that time period, don't do anything stupid. Magpa-good shot ka. Do a lot of errands and stay home. They'll come around eventually. When they do, ask to go out to something small that least likely involves alcohol.
