I'm in a dilemma.. i don't know what to become!?

Given the indecision and 'back and forth' feeling you exemplify in each of these fields, I don't think you'd like any of them as a career - especially if it only takes one bad teacher to sway you in a completely different direction. Better question: what is your favorite hobby or fun thing to do? At least that may keep your attention? Think about how that might translate into a career... Also, reading your post was PAINFULLY tedious because of the grammar. Maybe you could work on that?
