Went through all the psychological withdrawals in a day

Idk feels weird, I didn’t plan my quitting journey, I just did it and it was so random. I annoyed tf out of my friends telling them how I felt every 30 mins and just accepted it. I feel so much better my 2nd day in, went through all my routines I’d bring my vape with me in and just cried but it worked I think😭

Should I be cautious that it will come back tho?
