When You Quit Smoking Is It Normal To Get Depressed?

I think that is pretty normal.
You trained your brain to see cigarettes as a panacea (a cure-all) for any kind of situation (boredom, stress, sadness, happiness).
Now that you don’t smoke your brain thinks it is missing something. You really need to train your brain again and make it realize how much better everything is without cigarettes. There are so many benefits to quitting smoking, this shouldn’t be all that hard

Yes, so you should constantly remind yourself that it is the nicotine exiting your system and nothing else. It isn’t you. The depression is the bad stuff leaving your body. Well done!

very normal. one may also feel anger, annoyance, nervousness

yes its common, keep busy but not too stressed and you’ll get over it
