If there is no other religion to go too, why leave were I was born and raised.
It would be more sense to phrase it "If there is no other religion to go to, why be part of any religion?"
I understand it is easier to remain a JW for friends at your age. But few people can remain part of a lie for their entire lives, and the longer you put off leaving, the harder it becomes to find new friends. Finding another JW to fade with is also fraught with risk.
If you leave now, over time you will assimilate with normal people, and hopefully be able to get married and have a happy and heathly environment to raise the next generation of your family line in.
