Need counselling. Significantly?

So i am someone who gets panicked due to the fear of what bad news the imaging or any medical tests will bring. Not afraid of the tests though. I have been having this pain near my tailbone which is lingering since a year now. I have had an xray which said nothing abnormal, yet i am afraid of MRI. Cause I read about Sacral Chordoma and its prognosis. I know an MRI can easily answer all my queries and rule that out and easy my mind but the fear that it will find chordoma has consumed me already. I want to ask few questions: 1. If it was to be sacral chordoma, I should have gotten more and more symptoms apart from pain right? 2. If the xray doesn't show lytic lesions and me being 27, reduces the chances of having Chordoma significantly? Please guide me and enlighten me about this as this is consuming me and i want to be normal again :(. I so badly want it to be pilonidal sinus but i dont have any swellings. I am so overthinking. Please guide me!
