If I were you
I think you mean «toi aussi», which means "you too"
It means "But you are so funny to me" in French, no Cajun.
Je suis si heureuse pour toi!
Je suis si fier de toi, if it's a man speakingJe suis si fière de toi, if it's a woman speaking
that's broken French for 'you are cute'
vous êtes si heureux
'I feel so lonely without you'
Même si je ne peux pas être avec toi, mon cœur est à toi means 'Even though I cannot be with you, my heart is yours' in English
"if" is translated "si" in French
If
If I were you
I am crazy for your love I'm so happy that I have you
