Crazy new relationship anxiety

So i just got into a relationship on August 23rd. He is a sweet, caring man who seems to be serious about me. We hung out like twice a week since we met at the beginning of August. Now stuff has happened this week. Wednesday we had a wine tasting date planned but he had to cancel because of his work being extremely short staffed and then yesterday (Thursday) night we were supposed to hangout after he worked but poor him, his dad went in for an MRI for back pain and found he had fractured his L1 and also found that he has metastatic prostate cancer. So obviously he’s been at the hospital and unable to hangout. His dad is awaiting emergency surgery with 2 people still ahead of him. Here is where my anxiety is fucked. This is what’s currently going on inside of my head.

Anxiety: you haven’t hung out in a week and he’s cancelled on you twice. You’re never gonna see him again

Brain: that’s absolutely not true, both very good reasons to cancel plans. many couples go weeks or months without seeing each other.

Anxiety: No, you’re never gonna see him again.

I’ve had stuff like this happen to me before with other men where they began to cancel and then said “I don’t think we should do this anymore”

HOWEVER, this guy seems super serious about me and has called me both last night and tonight to update me on everything that’s going on, he even cried to me over the phone and told me he hopes I get to meet him a few times before he may die.

Why must my anxiety be so awful to me?

It’s torchure. I haven’t ate much, had the shits and lost 3 lbs over irrational shit that’s not true. This is the most serious a man has ever been about me in such a short time.
