I'm sorry to hear you in such confusion and despair.
It took me a long time to work out who I was and then accept it.
One thing I do know for sure is my friends and chosen loved loves and family will never abandon me for being the real me - they couldn't be my friends/loved ones if they did that.
Your mum is wrong - you're not an attention seeker. This is important stuff that needs to be talked out.
It's ok to be you, SerenityRiver
