BY THE WAY I have lot of proof of residency in the U.S even my colombian passport was processed in the colombian embassy in New York Lol, and also the stamps of previous admittance.
Edit - Wow thanks to everyone that has been so kind and have replied to my post I really appreciate your concern as well as time and effort, didnt expect this much help hehe, basically I was worried about the not let being out of the country I'm in, Thanks to everyone for the help and I meant it as I did not get a permit to come back to the u.s since my Green card was already expired before I left the u.s. it's just that I bent it by accident while being here, and I'm sorry about not being able to explain you better in a more detailed way since I was in a rush.
To make the story short, I've been in a country of which I'm a citizen of since Jan 2018, I had to come and take care of family matters, I really had no way of getting a permit to stay longer because it was an emergency, and ended up staying until now. I know I've stayed for too long, but this is not my first time and I´ve been admitted back to the U.S after staying a little longer than I should have.
This time though my green card is a little damaged but still in one piece, just bent at the middle, also it expired not too long ago, but my main concern is if I should be clear of getting through immigration from this country. If I talk to the immigration officer and explain to him the situation, I know when I get to the U.S they will definitely pull out my file and it will be confirmed that I'm valid, I'll deal with whatever I have to like before. I'm just desperate at this point, I really want to go to what I call home.
