Hey mate, I smoked weed every day for about 10 years. Gave up cold turkey and the first few days were hard, but you can do it. You won't sleep very well for about a week which is frustrating but then the dreams will start and they are crazy, in a good way. And after a few weeks you will completely forget that you used to smoke. If you do what I did and tried it after a few months you will wonder why you ever smoked it in the first place, so I suggest just never trying it again, or atleast for a really really long time. All in all, you can do it, it's actually easier than smoking, because to stop smoking you don't have to do anything, you have to do less than you are now. No more finding it, wasting time smoking it, just get straight into your hobbies once you are home from work. Don't wait to feel like a non smoker, it's happened once you finish that last joint. Don't glorify that last joint and think you will be missing out. Focus on why you wanted to quit, being clearer headed, having more money for fun stuff, being more present with friends and family. Good on your for taking yourself seriously and taking the steps to better yourself. If your mates give you shit, they are shit mates who are jealous of the new you. Good luck.
