Hello Aurora 😊
I am so glad you've reached out here.
I am going to give you point of view, but if it doesn't sit well with you, that's ok, and somebody else may have advice that feels better to you.
I know pretty much what it feels like to be in your position. I went to a religious school too, I knew I was a lesbian ... it was scary thinking of coming out.
My advice ... (I am now a grown woman living in a beautifully harmonious long term relationship with my lovely (lady) partner) ... is to wait until you are out of school. Other people may disagree with me, and as I said, do what feels right for you, but ... school does not last forever.
School is just a small part of your life, in the big scheme of things. When you're there, in it, it feels like it goes on forever, but I can assure you, soon it will be a distant memory and you can come-out in relative peace later, once that school environment is left behind.
I just think it will complicate your life too much to come out now, and will exacerbate your anxiety and depression, as you may be opening yourself up to all sorts of things in the school environment.
Do you think the coming-out it is something that you can sort of "let go" of for your remaning school time (how long to go?)? I don't mean let go of who you are, not at all, but just, like, "save it" for once you're free from that stifling environment?
This is what I did. It worked for me.
What do you think Aurora?
I am always happy to listen and I will be here for you to support you if you'd like to talk more about anything at all.
