I did just that about 7 or so years ago. Only gave my number to family members and really close people (maybe 5 at most). Also deleted all my social media.
One of the best decisions of my life.
Unfortunately, I was just getting started on “the real world” and would get any job thrown my way. One of them required me to reply to my manager on WhatsApp so I ended having to create one and give them my number. I’ve since left that job and I’m now no longer a junior in my field, but still feels feels bad on my record :(
