You say you don't want to be a JW anymore. That's a start, JWs leave for all sorts of reasons but leaving mentally and physically is not as easy as it seems. WT is a cult and the things you have been taught about Jehovah, Jesus, Armageddon and many more can stick with you your whole life. If you really want to leave the best things you can do are research from jwfacts.com and formulate your exit plan. Then once you leave you will be gone for good.
I am sorry the elders are treating you like dirt, I have been there, they don't listen to a word you say and just nit pick, how can they really be guided by holy spirit?
Take good care
