Fear of the unknown is so strong - what do I do?

Fear of the unknown is so strong that the right side of my body is tightening, extreme tension. Guruji, what do I do now? Don't bite with this fear. You see naturally, and if the answer doesn't come, it's fine. But naturally, if someone is in you, you can see my entire attention is getting used up in this sensation of fear. But allow the question to make some room. I thought, let's do. How much pace is this fear taking inside me? And if it is taking all the spheres, then where am I hearing these words? In which space are these words being heard?
