I can't say my mother is that overprotective! I'm wondering if you can get some sort of note or report from your doctor that says that her doing things like wanting you to shower with the door open is not necessary. I do suggest you talk to your doc about it.

As far as moving away, I'm sure your parents won't be thrilled, but you are 33 years old! Honestly, for one thing, they might not want to lose out on your free labor.

Would your boyfriend be willing to be with you and you can tell your parents as a couple? Maybe he can promise he can care for you, etc. But there might still be a battle. But, as I say, it's not like you are a little kid!
