It is crucial to have a support system. Whether it is friends or family. They can help see the signs and symptoms before you do. They also can just listen to you. That is one thing as a friend you can do to help. They just want to be heard. Usually nothing more. If you don’t have a support system join a support group and go to that. Anything helps.
My experience with support is that it is a benefits out weighs the it negatives. It helps navigate through the tough times and sail through the good times. You should celebrate the good times when you are doing well.
