Prevod - Portugalski brazilski-Finski - Estou Disfarçando!!!

I wouldn't say this although it is correctly formed... Could you explain the adjective a bit more? Secretive perhaps? But more natural in finnish would be to say something like I am not telling you everything or I keep things to myself...

My finnish sucks.

Sorry I have been away and did not see all the messages to the english translation unfortunately, because this is a bit tricky again.

disguise - naamioidun? (=be behind a mask) too concrete I think....
pretend - olen olevinani? (=pretend to be better than I am, too proud)
pretend, fake - teeskentelen? (=pretend to be someone else or trying to be different from what I am, cheating in that way)

Have to think about this a little bit more, i'll be back tonight.

Sorry, I'll repeat: my finnish sucks. I think it's better reject when they are wrong.
I won't waste your time again, Maribel.
Thanks for your patience.

Don't worry! Short phrases without context have many possible solutions.... I am here TRYING to find the most obvious and most used one...
