I’m confused

Ok so this is kinda scary because I’ve actually never talked to anyone about this but I just have some questions. It’s not exactly something you can casually ask someone lol. Sorry I don’t mean to make this sound like a joke or anything I’m just kinda typing whatever comes to my mind. So story time, I’m 14 and have been cutting for about 2 1/2 years. In the beginning they were light and didn’t scar, just kinda on the surface. My parents picked up fast because it was new and I didn’t know how to cover my tracks. They kinda spooked me, not like in an abusive way, but tried to fix it. It was weird I was just lying straight to their face, saying I wouldn’t do it again and I would tell them if I felt bad again. That was early 7th grade, then the end of 7th/beginning of 8th was really rough. I was cutting everyday for weeks on end, and I was just so unhappy. Well I’m still doing it now, but they get deeper and deeper every time. I feel like i have this huge secret, but I’ve been hiding it for so long it’s normal now. It’s like the “cutting me” is a different person though. Its like when I look at them (scars) now I’m not even looking at myself. I would post a picture but idk if that would even help. Anyways, I’m mostly trying to understand if I am depressed, because I do I go out and do stuff, but when I’m alone I change completely. Also it doesn’t take much to really bring me down because I’m super sensitive. Am I depressed? Am I just a normal emotional teen? Is cutting normal, because at this point I can’t even tell

if it’s normal or it’s just become normal for me.
