My child recently came out as transgender (he identifies as a boy now), and while I love and support him, I can't stop thinking about the daughter I've lost. I keep telling myself to focus on the son I have now, and I'm getting better about remembering his new name, but there's still a part of me that feels really sad. It's almost like I've lost someone. How do I get over this?

What do all the letters in LGBTQ stand for? How come sometimes there’s also an “IA” at the end?
