Every once in a while you end up having stress, but it can be for any particular reason. My main reason for the confinement of stress is homework. Homework has occupied an excessive amount of time from me for almost every day. Why I have stress with homework is because I don’t want to get in any trouble by not doing it or forgetting to do it. What I do is plan ahead and I always try not to procrastinate, because what happens for me is I end up sleeping very late, and when I sleep late, I end up waking up late as well.
At other times, you just don’t have time to do it, because maybe you have an extracurricular or an after school activity, so what you should do is prearrange when you will do your homework, do some of it on one day and others on another, so that if you forget -which is a 50/50 percent chance- you won’t be doing them all on the same day, while staying up.
If other stress that come into your mind isn’t about homework, but instead are about your feeling then maybe you should take time to cool off, sometimes when I just got into a disagreement with someone, I usually would take time for myself, contemplate about what happened and think it through. For example consider the other person’s feelings, try to think in their perspective. Or maybe, you don’t care about their perspective because you’re just mad and depressed; thinking will also help in this scenario. Everyone has different strategies; all you need to do is try them.
