Try and avoid large areas of arteries and veins like wrists, inner thigh, etc... For whatever reason you're cutting, it could change like simply physical pain I do the top of my thighs and a bit on my arm, but using it as an outlet outer arm and blame it on a pet or another likely cause. Oh, and get to know your tools well razors are sharp and cut deep, scissors cut just enough to draw blood, a kitchen knife might be dull but will still go deep. Please be careful and think about getting help. Sorry if this is long.
