It may feel bad to suffer a broken relationship. You might feel sad or lonely or may feel other emotions as well – look at What Feeling and Emotions Mean for some suggestions on what to do.
Remember first of all that you are still valuable and special – your worth is not dependent on what others think of you.
Take time to feel sad and then slowly put it behind you. Get yourself back into the swing of things by participating in various activities and expanding your social circle.
Remember, years later you may just look back and laugh at some of these situations.
