if it's already past 90 days overstay you will receive most likely receive a ban. It's the law. Mistakes do happen, that's why they allow the 90 day allowance, beyond that it's just down to you. Thailand clearly isn't the place for you, it's probably best to move on to somewhere else. They will allow you to leave freely if you surrender at departure immigration and pay the fine. If you are caught by the police within Thailand or you do not pay the overstay fine on the way out, there may be more severe consequences.
