This is going to be a life style change for you and your loved ones. First and foremost stop drinking and taking illegal drugs if you do. This will only cause negative consequences and can make this disorder worse. Surround yourself with upbeat, positive people. They will help you and will not lead you into bad things.
Another good coping technique is to take the opportunity to look at things from a fresh point of view. Try looking at things from a different perspective and you’ll perhaps see that it wasn’t the end of the world that you thought it was. Try and see what possible good may come from the situation and that you may have something good to offer someone new. What qualities could you offer that new person in your life? Almost certainly, there’s someone new out there who’ll appreciate you for who you are and all you need to do is wait for them to appear.
People with depression and crazy will often think they are God. They will have thoughts of grandiose. This will happen when they are in their manic episode. They will think that they can fly. Or they will think they can stop a car from running them over.
