I can relate to your situation, especially feeling the need to inflict harm on yourself, only mine is for different reasons. For me, I self-injure because I feel like I've failed everyone in being the girl they grew to love and know, and that by being the boy I really am, I am letting everyone down. So I guess it's a form of punishment on my behalf. But let me tell you, self-injury gets you absolutely no where, unless you count trips to the hospital as getting somewhere. I've been self-harming for close to ten years, and the only place it's gotten me is to the psyche ward. :/ I don't know how long you've been doing it for, but please try to stop before it gets out of hand and turns into an addiction. >.< 'Cause trust me...self-injury addiction is not fun. If you absolutely need to feel some sort of pain, you could try the old snapping a rubber band trick, or using ice to simulate the pain. Both of those have been suggested by my therapist. Unfortunately neither of those worked for me, but they might for you.
Sorry, I didn't mean to go on a tangent with self-injury. It just makes me sad to see people in a similar bad predicament as me.

As far as bad dysphoria goes, I get it really bad too. When school started, everyone kept calling me "she" and "her" and all those other female pronouns. After the third day of school I couldn't take it anymore and wound up going home and started crying and felt strangely empty afterwards.
