This isn't going to be popular, but I'm gonna post it anyhow.
When you switch from smoking to
vaping, you still have to deal with most of the quitting process of quitting smoking as smokers who quite altogether. Very little about vaping is similar to smoking. You have to give all that up and replace it with something else.
Your addiction seems to be extremely psychological and you don't seem to have what it takes to break it (it happens to a lot of people, not just with smoking).
The fact that you started smoking at the age of 13 tells me that whatever it was back then that made you do that is what is stopping you from quitting today. It is that something you have to address and attack (and it won't be easy).
I suggest, if you don't have the money already, that you try to save up and seek psychological help for your addiction. Get an extra part time job if you have to.
Good luck. And I really mean that.
