Is a size 10 a big size? ((American))

I'm 5'9" and 139 pounds and I feel fat 😭😭 I used to wear a size eight but those are getting a little to tight...so I might have to get some 10's....I can wear size small shirts and size small stretchy athletic shorts and to be able to wear those but be a size ten just makes me feel bad.
**Edit: I'm sooooo so sorry for saying a size ten is embarrassing....I feel suuuper bad about that and I should've worded it better...**
