Cover up a cut mark? - how to cover a tattoo without makeup

Ok first off I do not want to hear, I should not be cut! i kno its wrong, and I stayed for a long time (almost 5 months), but then something horrible, so I have to be last time.
So how to without the help of makeup or tattoos, too young to cope in, and do not say, or gypsum, cuz thats obvious. I have a closet on the night of Karate (first time) I do not think that I am a monster. I just want to hide without make-up, dressing, or tattoos!
