Here goes.
1 - In the first place, you have to realize that it is your fault and admit it, and then we can talk about if I can forgive you or not, but you will undoubtedly be punished.
2 - Not only would playing sports help you improve your health, but adjusting your bad eating habits would also have with a great effect.
3 - As a matter of fact, I already know that your heart isn't mine, but I would greatly regret it if I didn't tell you my feelings.
4 - One day, you will feel hurt when you are trying to teach your children something and they just ignore your advice. You have to remember your parents similar feelings every time you disrespect their advice.
5 - In addition to constantly learning new words, you also have to study the grammar rules - that would put you on the right path to being fluent in this language.
Your English is quite good, and I'd give it about a 7 or 8 out of ten. You have good spelling and know some complex words, and you'd have the same level of English as the average year 8 at my school. You may need to work on making your sentances 'flow' (sound smoother), but that's about it. Good job. :)
