Hey Emileee,
I'm sorry to hear this. I've been following your posts, and picked up on your enthusiasm for life right through your transition. Your positive experience in the workplace has given me hopes for my own future. Up until now, I have hoped that each little milestone in my transition mirrors your experiences.
It's just my opinion, but I don't think you should let a person try
to invalidate you. They haven't lived in your skin, and they couldn't possibly understand what you feel.
It's a bit sad to lose a few people who have been there for you for such a long time, but I think you'll make new, even better friends!
Keep your chin up. You deserve to be happy.
