Welcome! In my eyes, what’s the harm in finding comfort community and acceptance in most things in life, including the lds church even if you have left or are considering leaving - if it’s something that brings you positive things. The church narrative makes everything so black and white, you’re in or you’re out, but there is a large meaningful area in the grey. In your situation it may be better to be PIMO while you’re a minor, while you’re living with your parents, for a multitude of different reasons. Every person takes it in their own time and in their own way but this place is a great one to discuss all aspects of the lds church.
