If you do this long enough, Osakis, and really internalize it, then the fear of pain can be reduced to its proper place, which to me is: "When it comes, and it will, I will be strong enough to not only deal with it, but learn & grow from it. I won't like it, but I'll be fine and I'll come out with new muscles."
The logical acceptance of how your heart/mind is currently working comes first -- congrats on all the inner work you're doing right now. It's SUCH hard work!!
