Well even if your grandmother finds out I'm sure she wont hate you or anything. in fact she'll probably be glad that you are getting help right?

No i think you will just feel happier. No one's gonna die because your happier trust me. if you are happier it will be better for you and nothing bad will happen.

And no don't tell them to lock you up but try to focus on the fact that the fear is irrational and being locked up cannot really hurt you and your fear will disappear eventually
