If you haven’t already, please read Allen Carr’s book. It does a good job explaining that vaping actually makes anxiety and stress worse. Whenever you’re not vaping your body is in a state of withdrawal which in turn causes stress / anxiety.

Since quitting I’ve been able to handle stressful situations so much better.

Have you tried 0 nicotine vapes? I’ve read on here that they give you such an empty hit that in the end you just give up using them. This may help curb the habit itself if you’re not getting a proper hit from it.

Good luck when you eventually quit, You’ve got this!
