Help me in this please! My questions?

So, I am facing tailbone pain, not sure what is causing it, didn't have any major trauma as well. It's since 6 months. I was in UK when it started. I went to the gp, sadly he was googling the symptoms infront of me and i saw something called chordoma. Since then I am afraid of going for mri. I am an anxious person, so i have done xray and ultrasound it was normal but I fear if it turns out to be chordoma. So even though i have a prescription from practo for mri, and i know it will answer my questions regarding the pain, i am scared. How do I deal with it? Please help me. I am so scared of that deadly cancer that it's even stopping me from diagnosing it. Attaching my xray, even though the doctor said some angulation issue is there, idk i am still worried.
