i quit smoking but i don't feel stressed or depressed?

i always when i tried to quit smoking i always felt stressed depressed anxiety i even learned these words because i am sick and tired of them.

as any smoker or ex smoker i tried quitting several times. once i tried and a friend made me come back i tried for one week once i tried for 3 days and i went back. i was 13 when i started smoking so at the age of 16 i tried many times and failed so i kipped on going until 18 i quit for 3 weeks i felt so depressed and panic attacks. i never knew what was that feeling it was the first time i get it and on that day i also had fever so it made it worst for m. anyway i went back to smoking again until the age of 21 i quit for 6 months i didn't smoke anything and after these 6 months i started smoking shisha i don't know if you know what is that but it has 0.1 nicotine in it. i smoked that for 6 months so now it's a year with no smoking. i wont lie i smoked one or two or even lets say 5 cigarettes in this whole year. i use to hate smoking a lot i only smoked when i was drunk or something.

anyway after i wanted to quit shisha i went back to cigarette for 2 or 3 months i don't remember now it has been 3 months i didn't smoke shisha but smoked cigarette. i quit cigarette now it has been 4 days i feel a little bit of urge to smoke but when i think away it goes away it doesn't bother me allot. i mean it's weird i am not struggling that's why i don't even feel any problem in my head it's just a little bit of urge to smoke and it goes away when i don't think about cigarette. is that okay? i mean of course i am happy because i am not struggling to quit lool but it's weird i was expecting a much of a big challenge like before you know. so is it normal?
