Sitting around being sad and depressed was my normal way of life. Sometimes this would result in hospitalization to insure that I would not harm myself. I often had strong emotions of not being enough or worthy — I had a lot of self-esteem issues. I had a habit of taking all my thoughts as the absolute truth.
My emotions were felt thoughts. For example, someone that is afraid of heights can image themselves on a high building looking down — their heart rate will increase and their palms will get sweaty. The brain is easily fooled into believing thoughts are the truth, or the current reality.
