Letting go and moving on
Have you heard of people who have attempted to commit suicide just because of a broken relationship? Many times we get so attached to a particular person that when the relationship ends, one feels so depressed and broken to go on with life normally. We drown ourselves in self pity and blame ourselves for whatever went wrong. In such a state, we forget that before we met this particular person, life was smooth and that it can get back to normal after they are gone.
Learn to let go and get a life.
