How hard would it be for me to quit smoking cigarettes?

I’m 21 and have been smoking for about 2 years now. I smoke about 7 or 8 cigarettes a day. I want to quit and need to quit but I’ve heard the horror stories of quitting and how hard it is, but most of them have or did smoke way more than me and for much longer. Do you think it’d be easier for me? Have any of you ever quit smoking and smoked about as much as I do? How hard was it?
