Regarding hair removal... I feel uncomfortable showing my bare arms...

I always have a dilemma whenever I have to wear short sleeves.
It's because of the hair on my arms.

I have more hair on my arms than I thought, so I feel embarrassed and burdened by showing my bare skin because I am concerned about what other people think.
When I see my friends and people walking around with their arms out as if nothing happened, I feel like I'm the only one struggling with this problem, and it makes me sad.
I want to wear short sleeves to keep cool even in the summer, but I've developed a habit of unconsciously covering my arms for fear of the hair sticking out.
I've thought a lot about getting my hair removed, but if I shave at home, the hair grows back quickly, and if I go to a dermatologist or waxing salon for professional treatment, it's a burden in terms of money and time.
Because of these concerns, it has become my routine to wear long clothes as much as possible, even in the summer.

How can I confidently walk around in short sleeves?
