The first step in getting help is realizing that you have a problem.
----------
But, why? Are phones your hobby? Is it the thing that turns you on? That you're passionate about?
----------
What is the motivation for you? Because I can't imagine that you have any real time to get accustomed to a phone between switching them out. Do you do the same thing with TVs? PCs? Gaming consoles?
----------
What other, non-phone gadgets do you collect?
I think for a lot of us, myself included, technology in general is a hobby. Phones are unique b.c a new one comes out every few months that brings something different to the table. Tvs are different since you really have 3 choices (4k has no content and is too expensive right now) and there are 3 game consoles every 7 years. I change phones every 6ish months. It is not that expensive after you buy your initial phone.
