The world feels scary and depressing whenever winter comes

‌It happens every single year, only during the winter.
People say autumn is a lonely season,
but I don't feel that way at all during autumn.
It's just that whenever winter comes, it's so cold, and no matter where I go,
perhaps because my body physically shrinks up,
my confidence in life strangely plummets.
It has been this way since my school days;
the cold, in particular, has a huge impact on my psychology...
Am I being too neurologically sensitive?
