honey all you gotta do is is just start listening to people who don't have your accent. see im from pennsylvania, but because of my family i have a deep southern accent and when i went to school i was seriously ridiculed for it. when i started to talk to different people i started catching on, on how to pronounce different words their way instead of mine. in the end though i moved right back down to georgia, and got my accent back.
i hope i helped.
