I am going to assume that you have fragmentation from the way you are phrasing things. I also suffer from this and my teenager is trapped in a flashback loop. Thinking back to that age, my mental illness(es) were exacerbated by hormonal fluctuations, and so it makes sense that there is a lot of residual and somatic symptoms when dealing with this aspect of myself.
I also know what it's like to feel out of control and scared shitless about what you might to do yourself or someone else as a result of this. The obsessing and the anxiety are a death sentence.
My best advice is to work with your T on listening to and communicating with this part of yourself. Find out where the pain is coming from and compassionately work towards a resolution. I have dealt with addictions/dissociation issues all of my life, and I know neither of those are the right coping mechanisms. Neither is pretending it doesn't affect things or that if you ignore it, it will go away. Unfortunately life doesn't work like that, but the ability to love and accept those parts of yourself as purposeful, necessary, and a reality, will make integration a hell of a lot easier on yourself.
