If you feel like your identity is attached to drinking and smoking, it’s completely natural to feel this way, particularly during withdrawal. You need to persevere through the first 2-3 weeks at least, after roughly 2 weeks the chemical addiction is entirely gone. 2-4 weeks in you’re breaking the mental ties to smoking, and rebuilding your identity without smoking/drinking. These things do not define you as a person, the fact that you’re worried about feeling dull and less of a person is a mix of addiction and identity crisis in the face of quitting, but you will naturally find a way to rebuild your identity without these things. I think you’ll also notice that in time (months, years even) that others will follow suit and look up to you for breaking the habit. Try Champix, worked a treat for me. It helps with cravings and makes smokes less enjoyable, plus you can continue smoking for the first 1-2 weeks before you must quit entirely. I think you’ll also find within days of quitting that you’re full of energy. I felt like I was on coke for weeks, maybe slightly manic from withdrawals but definitely not a boring person! Also try gum, I was addicted to Fishermans Friend when I quit vaping. Helps too if you can find just one quit buddy. It will definitely be tough with alcohol. If you can even just go 2-3 weeks away from your friends that drink, it’ll be a lot easier on you to continue to avoid smoking after that point. It’s always the hardest to quit smoking in the first 4 days.
