I'm scared and nervous as fuck...

So for the longest time I delayed starting hrt. I knew I was trans at 21 and I'm 27 now....any way I had my appointment to get my hrt yesterday and I have my appointment on Tuesday to freeze my sperm....and let me tell you I'm nervous as fuck but I'm out of excuses now. For the longest time it was freezing my sperm before starting and I'm finally doing it.i literally want to throw up as im typing this. I have so many thoughts going through my head yet at the same time ive wanted this for so long yet im scared to move forward. I've posted like 1000 times on trans related subs just asking questions and for advice and going to therapy and im just a few days away from finally starting and im scared shitless.
