scared i’m gonna die

I'm currently living through a massive health scare with really scary symptoms. I am scared I might have an aneurysm due to my symptoms but despite that the doctor's don't think it's urgent. I have some test scheduled but I will have to wait weeks for some of them. I don't know how to get through this knowing I could die any moment. I live in constant terror ever since those symptoms started. I can't function. Can anyone here please help me with this??? I don't know what to do?

i’m so scared im going to lose control and end up locked up or something. this is so exhausting!! i worry that what i have isn’t OCD and that im genuinely insane and im gonna end up in big trouble or that the urges i have are going to actually happen. i dont want to think these things ! i feel like a horrible human being!!

Of course we can’t stop the inevitable but with my ocd it’s all I can think about. I’m afraid I’ll be alone for ever and I’ll fear forever. Fear does not stop death it stops life. But how do I stop fear??? I can’t think of anything scarier than the fact that our conscious will vanish for eternity. I am only 20 years old but I mean the last 5 years flew by like nothing.
