I need advice on how to properly quit cigarettes☹️

I’m 20.. I’ve been smoking for almost 4 years now. I smoke about 10 a day and honestly I hate it so much.. but at the same time I really like sitting outside and smoking a cig, and the feeling of inhaling it I’m hooked on. It’s ruining my skin like.. I have wrinkles in places a 20 year old shouldn’t have wrinkles. I’m scared I’m already past the point of being able to reverse what cigarettes have done to my body, but I feel like I can’t stop. I’ve quit before for 9 months but that’s because I was pregnant and after I started right back up again, craving them like crazy my entire pregnancy. I’m at a loss, I feel so desperate to quit but I can’t get myself to. I can’t even go 2 hours without smoking. I need help or advice or just something to maybe get myself in the right direction of quitting for good
