Delusions are by far the worse. See the truth by what it really is. Relationships end for a reason.
Learn how to love yourself. Discover new hobbies, dedicate yourself to your passions. Take good care of yourself. It is good for self esteem.
Enjoy the company of your friends to the fullest. They are the best.
Be grateful for all the learning that is coming through this.
So far these are mine conclusions from someone who has also been through a rough breakup 🙂
