Maybe. You probably can't "fix this". You probably have to just live with it, and the sooner you start working with that reality probably the better. It's been years now for me. I've learned to use parts of it, and to compensate for other parts. Some things have mellowed, some things haven't. It's kind of like I died while remaining alive and there's a thread of the younger man left. It's easy to fall in a hole I know. I don't feel every day like I have fallen into someone else's strange life in the suburbs anymore, but I still feel it. Personally, I don't care about diagnoses. For me it's "Ok. Who cares? And what?" feeling response. What am I gonna do? You know what I mean there I think. That's the question you asked.
I do my best to be good to people. The buddhist dictum to serve others for its own sake helps me. I have one of those quotes from the Dalai Lama, a guy who knows a thing or two about bad stuff happening, "Never give up. No matter what is happening in the world, never, ever give up." I don't know that I'm a buddhist, but I resonate with it and respect it, if not all aspects of the cultures built around buddhism. I've mostly given up on finding peace. I'm a storm, but peace happens from time to time, mostly when I have accomplished something I set out to do.
For myself, I relax more when I'm under more threat and stress. But it's also exhausting and I know I 'm too old to really be there in the thick of it and survive. I've gotten slow. I don't make the connections I used to until a day or two later, where I used to get it in minutes. Guess I've gotten older. I said elsewhere that bicycling almost daily helps me. I get out and hike, got places. But most of all I think about what I need to do to calm other people, to help them, to be as good a person as I can. Don't always succeed, but it's a branch to hang onto you know. For myself, I've figured out that there isn't a whole lot that can be done about me. I hit the end of my rope and broke it so long ago it's lost in time. But a person can function in a kind of emotional free-fall. When I let someone I care about out of my sight, I have to say goodbye to them forever, as if they were going to their death because I know they might not come back. It's the only way I can deal with that and keep it together. Acceptance that I can't manage it is my ticket, along with lots of "reality testing" to make sure what I'm doing makes sense. (Mostly.)
Maybe my story can be useful to you, maybe not. You are going to be unique. Good luck.
Sometimes medications can help. If you have ADHD, there's stuff for that. Try to find someone who will work with you.
