It's normal for you to combine the reality and then analyze the problem. Sometimes you don't know why you do it, but you are still right. Doing math is to dare to guess. Don't do it if you can't. Why are you so hard on yourself? Life is so beautiful that you should enjoy it. In high school, you will find that it used to be so simple, the formula is less than physics, and now it feels so little to remember things.
