It is important that you start to look for life lessons that you could learn from your relationship. How does this relationship make you a better person?
What are some of the things you could do differently? What did you discover about yourself during the relationship?
Do you need more emotional freedom? Would you like to be more assertive?
The key to overcoming depression after a breakup is to start looking for positive aspects of your relationship.
When you start to look for positive things, then you will feel appreciation instead of depression and you will slowly overcome depression after a breakup.
Choose appreciation.
