There was a number of issues that contributed to this development - new LOAD of responsibility I've never experienced before (where I want to be there to watch my kids grow, to help them develop into happy people they deserve to be), some turbulence in my personal relationship as well as distrust for the healthcare system that's accumulated over the last three years.
I guess I am out of the woods now though. Maybe the shitty spring and return to work were also part of the problem and now that these are in the past, my self-persuasion of not letting my fears to control my life are finally working. Maybe vacation with my dear friends worked the magic. Whatever the reason, I am grateful I got it under control. Not sure I can say I conquered it yet.
