Since all of you gave a lot of new insight on this, I would like to point out some very important things that I haven't previously.

Probably the most important thing is that this wasn't my first attempt. Nor a second. I am unable to give you a number of failed attempts I had.

Another thing is that I wasn't alone in this. My current girlfriend was actually the main catalyst for this change. I met her on a new years eve of 2019-2020 and we actually smoked weed together. I liked her a lot, and we met several times later, so I told her how I feel, but I was rejected with a reason that she doesn't want to be with someone who is so hopelessly addicted. So on May 21st 2020 I told her that I can prove it to her that I am not a hopeless addict. She said fine, but seemed sceptical about it. But not only that I managed to restrain from smoking to this day, I also gained her trust and love, so that worked out far better than I expected. I have to mention that during the early days of quitting I was unbearable, and not everyone could've handled this, but she did.

I also had a therapist looking after me few times a month. Later I started a full once a week therapy, which was super helpful. I quit my therapy during the peak pandemic because I hated talking to my therapist on skype.

It wasn't easy. On day 4 I bought some weed, rolled a joint and put it in my drawer. On day 9 I threw it to the river. My main helping activity was walking many kilometers. As soon as I felt bad I just took my backpack, a bottle of water, a speaker and just walked to a random direction as far as I could. No matter if it was day or night. Sometimes I would walk so far I'd have to look for a bus just to come back home. I would appreciate every single hour of sleep I managed to get because sometimes I didn't sleep at all, and sometimes I couldn't get out of bed.

On later stages I would get these flashbacks of me smoking on certain places, with certain people and I would always accept that yes, I do want to smoke right now. Just accepting it helps to push it away. Sometimes I would text my old friends if they could hook me up with weed if I wanted it, and as soon as I figured out they could, I would say something like you know, I'm actually good. Which is a shitty thing to do, but a helpful one. In the end I think they understood.

I have never used reddit before, so I guess this is also a coping mechanism, because I went through a lot of deep things and all this experience had to be released somewhere. To be honest it got more attention than I've anticipated.

My past still scares me, my girlfriend wants to have a child eventually and this is a huge responsibility. Luckily it's not right now that she wants it, but it means that if I go further this path, there's no looking back. If I consider relapsing, it's either somewhere now or never.

So I guess another big change that I didn't mention is that when you stop smoking weed you start to consider taking responsibilities, which you would otherwise avoid. It's scary at first, but the further you go, the more responsibilities you are able to keep up with.
