Bonjour Help me svp, je suis nul en Anglais .Vous pouvez m'aider,merci.

Voici ce que tu pourrais dire:

Hello, I hope you're doing well.
I am here to ask you a couple of questions about your phobia. Firstly, when did you know you suffered from nomophobia, and how did you discover? Does your phobia means that you can't be with some people without leaving your phone? And finally, I would like to know how do you leave with it?
I could tell you from my experience that going off your phone for one day is a great start. You should just try to distract yourself, maybe by spending some time with your friends, going shopping or just do whatever activity you enjoy.
See you :)
