Q. hi I m Ian Bob 21/m. I am suffering bipolar disorder, what can i do to prevent this disorder!

A. Hi Bob, its nice to have you here.
Unfortunately there is nothing you can do to prevent bipolar disorder, however you can manage the illness. There are a lot of different things you can do wo manage the symptoms. You can see a theropist and psychiatrist, for meds and talk theropy. You can get regular excercise, meditate, surround yourself with positive supportive people. Teach your friends and family about your illness and what you need from them in your times of need.
You can also come here and ask questions and answer other peoples questions to help get out some of thie thoughts you have. You have a support system here with plenty of people who know what you are going through and care about you.
I hope this helps you!
