Hi @Snuchu,
that's a good question... I hope others out there may have better ideas about this than me.
I gave up smoking weed about 13 years ago now. I was a daily smoker at one point, but I could easily go around 3 to five days without it. It depended on what was going on in my life at the time. I don't believe I ever developed much of a tolerance to weed, because I would get high very, very easily and hence I rarely smoked when I knew I had to go out in public.
Also, none of my friends smoked weed very much and so I didn't smoke it when I was around them. These things probably kept my cannabis use in check.
When I gave up weed, I also gave up drinking alcohol and also caffeine! I stopped 3 poisons at once! I was heavily addicted to coffee and I would average drinking around a bottle of wine a day, too. I did not even believe I had a problem.
I only gave these things up because a naturopath suggested I do so. I thought I would give it a try and at that time I sincerely believed I was not addicted to them, anyway.
I suffered from nausea, headaches and lethargy for 4 days. After that, I felt a lot better quite quickly. During the withdrawal, I took over-the-counter pain killers for the headaches and slept a lot. I didn't eat much but I drank a lot of water. I honestly don't remember it being very bad at all.
As far as my emotions were concerned, well, I think at that time I was so completely disconnected from myself emotionally that it just wasn't an issue for me.
Of course, emotional problems were what caused me to come to rely on drugs and alcohol back then, however I had no idea of this at the time. It seems unbelievable to me now - but that is how is was. I never acknowledged any of my feelings back then and didn't become depressed until years later, when I was basically sober. 
Anyway, I have never gone back to smoking weed and I don't miss it. I still drink alcohol but not every day and I really do try to limit my drinks.
Snuchu, I think you should ask your doctor what is the best way to get off weed. You might need to take a mild sedative or something else while you are going through withdrawal. I don't know.
If you suffer from depression and anxiety, the weed might just be masking it, rather than causing it. This is something you would have to explore. Do you see a counsellor?
