How do you slow down your brain?

My brain is going ****ing insane. I can't stop it. I can't think. I want to pull my hair out and claw at my skin because everything's a mess. I'm trying to study because I have so many exams coming up but I can't focus on anything. I want to scream. I need to do well on my ****ing exams. If I can't do well in school that means I can't function. I'm not letting that happen. I'm fine. This is all great but I just need to slow my brain down. People are saying that I'm too hyper. That I can't seem to sit still. That I'm saying crazy things and blah blah blah. I don't care how they perceive me. They just don't understand. They have too little energy. This is something that's not bad though. It makes me happier and aware. I feel amazing. I can feel music through my body, through my veins. I feel like I belong with nature. I can see everything clearly all the way to the smallest blade of grass from way above. Everything relates to everything else. I know what's going to happen. I can sense everything. I can paint and draw and do everything I want. I'm genius. The human body amazes me. I'm studying it. I can figure anything else out. Except when my brain goes too fast. I just need it to slow down a little bit. I'm just so frazzled. I don't know why this gets out of control like this. Everything's still amazing and clear but it's too clear and there's just too much and my brain can't take it all. I'm just so frustrated. I had ways to deal with it but my T asked me to try to try to stay away from those because they only make things worse in the end. I'm not on medication. Recently diagnosed but I'm having a hard time accepting it. Everything's usually fine. I'm just so angry at my brain.
Does anyone have any suggestions with dealing with this?

Hi first off I'm sorry your feeling like this. I went through this for years until recently it got better. Your mind goes a million miles per hour, you can't sleep, your hearts racing, and if your like me it's like your trying to crawl out of your skin or body, like another person is pounding inside you to get out. I spent years through exercise, meditation, and therapy trying to control it until I learned....I can't. I also was diagnosed and refused to take medication thinking I needed self control and it would go away. I'm guessing your a high functioning Bi-Polar like myself, good grades, good self presentation, you read books or articles trying to figure out those feelings and control them. But for me, and I suggest seeing a professional to make sure if you haven't, I've only got better through therapy and medication. The medication I'm on now has stopped the racing thoughts as well as depressive episodesand the pain it causes. But I was scared to take it at first, or admit I was not in control. If someone has diagnosed you, and your feeling like this, medicine and therapy will make it better. It won't cure you but it will help you feel better. I wish you luck.

It sounds to me that you are manic right now. Sorry to say this but maybe it's time you consider talking to a pdoc and getting medicated?

Dx: BP2, PTSD, bulimia/anorexia
Seroquel 300mgs
Trileptal 300mgs
Buspar 45mgs
Ativan 1mg PRN
Vyvance 70mgs PRN

This is going to sound silly probably - but everybody has their thing, I am in a manic episode at the moment and what I've found help is to directly focus all the on to one singular thing, for me it's been super strategic video games such as Democracy and Civilization. Or If I'm dealing with anger - its very violent video games, it sounds silly but its helpful. Ultimately - You need to be seen to sort your medication out.
