Bipolar is a difficult illness to cope with. Staying informed will help you Validate what you are going through.
Finding a support group will allow you to tell people what you are experiencing, and also help you when the road gets tough.
When you have been diagnosed a big decision awaits you. Do you tell friends and family or do you keep this to yourself.
Redefining your lifestyle is something that needs to happen whether its voluntary or not.
Another way of coping can be to find virtual friends who also suffer from Bipolar, with whom you can discuss ways of coping etc.
