A Loss? I don't know who to talk to

Two days ago, my 21 year old told me that he's transgender. Im having a difficult time dealing with this. Not because Im against transgender specifically- I have trans friends- but because I feel like Im losing him. Like he was diagnosed with cancer and only given a few months to live.

I have a letter he wrote me in 4th grade telling me why he loves me- he signed it. Im grateful that I have a lot of photos of him throughout his life. I am tryi g to make this NOT about me but I cant help it. Im in total shock. I fear something bad will happen to him - people dont always accept transgender people. That's putting it lightly.

I can't wrap my head around this. Its a huge loss. Of course I know that he will still be my child no matter what but I dont know this new person. He has known forever. Everyone in the family (that know so far) is in shock. My mom doent know what to think. As I said I have a friend who is transgender - but Ive only known her as a woman and she's not my child. She is however a great resource.

Nobody can take our relationship away. But I really fear for his well-being and safety. He's only 21.

All for now. Im still stunned, sad, overwhelmed, happy for him, angry... All the stages of grief rolled into one.
