Why will my brain never slow down?

In my experience, it's usually because of a lack of closure. Maybe you didn't like the way you ended a conversation with someone, or perhaps you're anxious about an event, etc. It could be any number of things that keep your mind racing all day and well into the night. My advice, as well as personal way of dealing with it, is to have a hobby you love to do. Make sure you have a cool down hour or two every day where you just focus on one thing and let the world pass you by without focusing too hard on it. Just take some chilled out time for yourself, it's always important :)

I can totally relate to this. While taking tests, I always have to reread the same thing many times because my mind wanders 24/7. It does happen though, everyone is different.

Sometimes our brains work overtime. You over think, over analysis, and may have trouble sleeping at night. Does this sound like you? Try to think of this as a positive if you can. Your brain can possibly work on multiple things at one time that others cannot. Also, some people whose brains work like this also experience hyperfocus, which can be a very good side effect. Try to make some nighttime habits for a restful sleep but realize that your brain is working and you can use this in a positive way with some practice and a restful night of sleep.

Because your caught in your fight or flight reflex. The lower part of your brain, the brain stem. It's a symptom of anxiety. Your brain wont slow down until it feel it's safe.

Deep breath in through your nose, out through your mouth. Focus on 5 things you can see, 4 things you can touch, 3 things you can hear, 2 things you can smell and 1 thing you can taste. This will focus your mind on the present, the things you can currently affect, xx

When we are anxious our brains can tend to go into overdrive, and you can otherthink as everything speeds up. I found it helpful to learn some relaxing tecniques, listening to meditation and relaxation music to quieten the mind. Also deep breathing is very good, to concentrate on your breathing. This can also be used when having a panic attack, breath deeply through your nose then out through your mouth slowly, Imagine all your stresses and strains flowing out of your mouth as you exhail, then good as you breath in. Also to quieten your mind I find reading really help me, esp befor sleep.

Probably you've been thinking too much recently. It stresses you. You accelerate your thoughts too much. Give them a break and start talking to people instead of resolving things in your head.

Usually for me is I am trying to do what too many things at once and will overwhelm myself without even noticing till I am already at that point. What I found is sometimes I need to take a moment and just breath before taking on another activity.

Having anxiety, OCD, or any other mental illness that causes "refreshing thoughts" is not your fault. There are ways to help get through them, however, and it depends entirely on the person. Temporary distractions, hobbies you can get lost in, etc. work best for me.

Your brain probably won't slow down because you have a lot going on in your life that you're trying to handle at one time which is causing your brain to go all around
