Me siento mazo sigma or mă simt sigma.

Je me sens trop sigma (French)

我感觉很sigma

I'm from Malaysia, unfortunately I don't know Malay that well and I'm currently using Google Translate for it (I am not asking my parents how to say it they'll be so confused), but it seems to be "Saya rasa sangat sigma", which, from what I know, is pretty much correct

Estou sentindo muita sigma! (I think it’s feminine? It ends in a)

yo siento muy sigma >:]

i love this question, it's so silly... in Spanish, it's "me siento tan sigma". :)

in Ukrainian this "я відчуваю себе таким сігмою / я такий сігма" or smth

I’m not that fluent so it might be inaccurate

Mwen santi telman sigma

I speak English natively but it is "Ich fühle mich so Sigma!" in German!

eu me sinto tão sigma

native English speaker here, but I also know a conlang called toki pona. problem is that I can't do a good translation of this phrase because "sigma" in this context means... pretty much nothing as far as I can tell? in fact the entire phrase is nonsense

so it could be "mi pilin sama sitelen Sima pi toki Elinika" (I feel like the Greek letter Sigma) or "mi pilin mu mu mu" (I feel random noises)
