Hi Warren,
Like UsernameOptional (Mike) advises, bang on your keyboard writing your blog and other things. Of course it won't fix it for you but it may help you emotionally. I'm so sorry you're feeling this way and wish I could offer more.
Did your therapist give you an emergency number to call if you have a crisis? Perhaps that would be good to do. Or, what about the Transgender Suicide number? I'm not sure if it's only good for US residents. Okay, maybe you're not suicidal (I hope not) but you sound very very upset and need someone to talk to.
I hope you feel better soon. Regardless, keep writing. Don't worry about what you're writing, just keep it coming.
Hugs,
Emma
