Then when I leave I will disasociate myself and things wouldn't be any different than if I hadn't gotten babtized in the first place,
You will be treated differently as a disassociated person than as someone unbaptised. Maybe ultra strict JWs such as your parents will treat you the same as first but most JWs are far more likely to speak with someone never baptised.
Being baptised won't make much difference in how the teenagers treat you, and as you know, as soon as you stop going to meetings they will all dump you as a friend anyway.
