You may even find yourself with your own unwelcome thoughts, wanting your friend or loved one to disappear or even die. At the very moment you want to be there for the person you care about, your own feelings are in a muddle. Your own life is now impacted. You may not know what to do or where to go for help, leading to more frustration, fear, concern and additional tasks that you really don't have time for. You should be aware that depression comes in many forms.
Some episodes occur suddenly for no apparent reason.
Some are triggered by a stressful experience. Some people have one episode in a lifetime, others recurrent episodes. Some people go up and down vacillating between manic and depressed periods. And, a little known fact, depression often occurs after a serious illness or in conjunction with being overmedicated. They cannot monitor themselves.
