What should I do?

HI! Sorry to hear this thing.. Do you mean you failed your subjects in school? or you failed to go to your classes?

Well, you need to ask yourself what you want to do. Why are you going to school? Maybe you don't want to be there. If you were really interested in the things you were learning, it shouldn't be so hard and you'd find ways to learn. Maybe there's something else you are interested in???

When you failed classes and subjects after trying your best, then that means you simply are not interested on what you are currently doing. You may don't realise this but you are kind of forcing yourself to keep doing it over and over again, because if you are not forcing yourself and you actually passing the subjects and classes means you have an interest on it and you actually really want to do it. You better start considering what you are doing at the moment. Maybe those subjects you are doing at the moment are not of your interest, it may be something else...another subjects you know, otherwise you will only be wasting time.
