Cutting; is it normal? Mental Health

ok, so i cut. but i dont think i should really consider it cutting? i broke apart a normal womens disposible razor and i cut with those blades. so you can tell i dont cut so deep. part of me wants to, but i cant manaage to find anything big enough to. there are 3 people that know i cut, but they think i stopped. i did for a while, but i kinda started agian. not much. just when im bored really. but i dont cut deep, so is it still considered cutting? and i started cutting becuase i was feeling really depressed, and misserable. everything was going wrong. but now i just cut because i want to. not becuase of any emotional feelings. is that normal? and i used to cut for emotional reasons amost everyday. i only stopped becuase it was too hard to hide the scars and healing cuts. im not saying i give myself papercut-like cuts either. cuz there deeper then that lol there just not too deep. but now i cut around once a month or so depends whats going on but yea. so is it normal?
thx!
