Fat arms???

These are my arms. I am VERY conscious about my arms. I usually wear cardigans or sweaters (yes in the summer) to hide them. It’s been like this for years and it’s now that i’m feeling a lot of hate for my body. I’m pretty small everywhere else. I have a small waist, butt, and thighs but for some reason my arms are huge (compared to the rest of my body)

I’ve read that it could be because of lack of testosterone. I’ve also read to try to lose weight overall but I don’t know how much weight i could lose since i am 5’3 133lbs.

I was wondering if anyone had any advice how to make my arms smaller. I don’t want my arms to be muscular or bulk up. I literally just want my arms to be thinner 😢 like this

any advice???
