If you leave you will trigger a ban. How long in the US were you without status before you got DACA approved? If it was a few years then the ban in 10 years. With DACA you are not given legal status you are just not acquiring any more unlawful presence.

Are you sure your lawer told you that because you got approved for DACA you did not have to leave the US? This is not true.

I am under 245i and can adjust status eventhough I am EWI because my mom filed for me before march 2001 AND had to pay a $1000 fine. Congress made this happen.

If you leave you can get a waiver. BUT be aware that it is only granted if you an prove that your absence will cause extreme hardship to a US citizen. This is very risky.
