I believe we all Question sometime in the transition ftm or mtf. It is an emotional and stressful time. Was there a trigger or just a gut feeling. Take it one day at a time and if your not talking to someone already it may be good for you to look into counseling. You can talk to a trusted friend or family member etc. Just talking and listening can open your eyes to your true feelings. Give it time it is a long and slow process with ups and downs.
