Hi Jayce,
Welcome to Susan's a wonderful place. I think most guys have all struggled with the TG issues at some point in life. I am a much older M2F crossdresser and I am married. She isn't supportive so I am closeted but I enjoy my femme side and think I will never lose that. Anyhow, good luck with your appointment and be open about it. Also, feel free to ask questions here as there are many, many nice people here.
Hugs,
Jean
