You said you spoke about your feelings to your school counselor, you could possibly go to that counselor and express your fears to her about what might happen if you open up to your parents. When you are ready, have her arrange a meeting with your mother where all of you can sit down and address both your feelings, along with your concerns.
But do not rush, if you need to explore a bit more then I would suggest reading on various articles and exploring more on how you feel, doing this well help provide more clarity.
Also remember that no matter who you are, you will always be loved and even if things seem bleak at the moment, just know that there will be light in your future, I promise.

With love and a thousand blessings
