Hay fever indistinguishable from cold

I am suffering from hay fever now.

It is so serious that I can hardly do anything without trouble.

I cannot concentrate on work. I have to care about my nose every minute.

Interestingly, and quite unfortunately, I cannot distinguish the symptoms of my hay fever from a common cold. I have a headache, as well as a sneeze. I feel very tired and I become easily exhausted. The only difference is the itching eyes. Therefore, I guess I have no cold.

I hate March and April. I would like to keep sleeping until summer.
