Why am I starting to question again?

Ryyu.....Please don't let labels cause you a lot of distress. In the first place, you don't even need a label if you don't want or don't prefer one. Some people find a label something that gives them a feeling of belonging. Other people could care less as they feel that they are who they are and a label makes no difference at all! Likewise pronouns...there are a number of people to whom pronouns are quite important and others that really don't care at all. It seems to me that it makes more of a difference to someone who is trans or someone who looks somewhat androgynous. These people are often quite tired of being mis-gendered and so pronouns are important to them. If pronouns are important to you, then you'll have to let people know when you meet them what your pronouns are. However, you should realize that there are people who dislike the whole "pronoun business" and may not react in a very polite way. Such is the way our society is today. If you feel that you are non-binary...that is a decision that only you can make. No one else, including your friend can make that decision for you. It matters not at all whether your friend is non-binary or not, as you must make your decision based upon how you feel in your body. Do you internally (in your innermost being - your mind) feel male, female or neither? That is the question that you have to answer. I hope at least some of this has helped! Hey...please keep us updated on how this goes, and don't forget...you are a part of our wonderful LGBTQIA+ Family and we do care!
