If you overstayed less than 6 months, I believe that you are banned from the US for 1 year. But since you have already been in your own country around 2 yrs, that ban is now lifted.
You still have to get the tourist visa in order to visit the US again though and show proof of ties to your country and you have that, so there should not be a problem
Contact the US embassy and they'll let you know what to do.
