Please check if my translation is correct?

Question:

I wanted to say, "It's too embarrassing I don't want to talk about it"

"Datte...chou hazukashi kara hanasanai desu"

Though I want it to sound casual since I'm speaking with my friends..

thank you!

Answer:

That sounds excellent to me. The only thing to point out is that the part "want to" seems to be missing in your translation.

--kara hanashitaku nai desu.

don't talk - hanasanai

don't want to talk - hanashitakunai
