Don't expect others to do what you want coz you might disappointed in the end. The best thing to do is just go with the flow and never expect others to be your superhero. They are just an ordinary people that may also give disappointments to you.
Be mature enough and leave being a kiddo. You’re not getting younger so put your foot forward in ever decision you will make. Everything happens for a reason and it doesn’t always have bad intention. Put in your mindset this things happened because fate wants you to learn. Learning doesn’t require age so be open for it. Remove from your head that people want you to get hurt and some other stuff. Sometimes they made decision cause they think it’s the right action for the sake of majority.
