Jerred,
I am super proud of you for your strength and determination. You may not see it, but you are a very strong man. There is no shame in crying. Crying can be a purifying thing. Look, you know what you want in your life. No one else can determine what's right for you. So, even if your mom is not on the same page, that is okay. Only you can decide your own path in life.
As for her denial, that's not necessarily a permanent thing. Many people have had parents deny there identity to all of a sudden holding their hand before surgery. Quite frankly, denial is par for the course. Remember, it took her time to adjust when she thought you were a lesbian. So, don't give up hope. She just might need some time.
I am so sorry for your pain Jerred. I'm a very sensitive person and have a lot of empathy, so I hate seeing anyone sad. If I could take away your pain, I really would. But know this, even if it hurts now, it will get better. No matter how she responds, you confronted who you are. As difficult as it is to see this, you just accomplished a major thing. Awesome job for being you and not letting fear stand in your way. Nothing will be able to stop you from doing what you want if you work hard. And you can do this.
Hugs.
