英文小作文：

Every spring, I suffer from severe hay fever attacks that make me feel miserable. Itchy eyes, runny nose, and sneezing are just some of the symptoms that I have to deal with every year during this season. I always take medication for hay fever when it hits, but it"s still hard to avoid feeling uncomfortable. I try to stay indoors as much as possible and use a humidifier to reduce the dryness in my airways, but it"s still not enough to completely alleviate the symptoms. I hope this season passes quickly and I can finally breathe freely again. I know it"s just a temporary condition, but it still makes me feel helpless sometimes. Hopefully, I"ll be able to manage it better next year and avoid having to rely on medication for too long.
