day draming works for me

Make yourself laugh. Even fake laughing.
A shower might help.
Also dancing.
Try copying a page out of a book backwards with your wrong hand.
You don't have to feel like doing any of those things, but just doing them might help jar you out of your cycle of thoughts.

hitting your head against the wall 50 times might work (jk)

lol lance :0)

that depends on why your mind is unfocused.

i clear mine by writing it down whats in your head it seems to help me

Focus on breathing. And yoga seems to help me.

Music works for me. When my brain is on overload, I plug into my mp3 player and forget what's around me...even for a short time.

I hate being in a "fog." It makes it so hard to do anything.

Something immediate for me is to get into nature alone. Sit in a field, near water, backyard. Somewhere you can sit and chillax. Or sometimes I go into a dark room, pray or meditate.

It would be important that you are eating good and sleeping enough too--keep your mind fed in that respect.

Sometimes, I will go to this puppy store and hold all the puppies. Or a library and read something not to heavy.

I guess it depends on what makes you happy, calm and relaxed...

Sometimes it takes meas long as three days to get out of the fog...

The best to you...

I sleep and hope it'll be ok when I wake up xx

I do the same as susy and it usually works for me.

Meditation, meditation, meditation. And exercise.

loud music in headphones.
your brain is unable to think and the music takes over

Have you tried meditation? It connects you to the present moment.
