What is the best way to get over anxiety due to fear of someone walking out of your life?

The best way to get over this anxiety is to work on your self-esteem and the realization that your happiness depends on you and not on the person who may or may not walk out of your life. We cannot control the actions of others but only our own.

People come and go throughout your entire life. Enjoy the experiencing you share with people when you can. If a friendship or relationship ends negatively, view it as an opportunity to grow and learn.

Fear of abandonment is very disempowering. It leaves you dependent on someone else's opinion for happiness. Accepting that you can't control what other people do in your life or how long they'll be there may be the best way to ensure you future happiness.

Know that you are strong yourself and don't need to rely on anyone! I know it's difficult, but it's possible. It makes sense you are feeling that way. :)

It may not work for you, but for me reminding myself that nothing is Certain in the future and that I might as well enjoy today can help. I tend to get caught up in the Future and dwell their in anxiety, but when I return my focus to the present I am happier and more reasonable and realistic. It also helps to remind myself that come what may, I will survive. And, that by NOT assuming they will leave, I lessen the likelihood that my anxiety will drive them away. So, I try to keep those three things in mind (as well as use coping skills to manage my anxiety).

It might help you to discuss your fear to this special person, and let them know that you appreciate having them in your life.

Surround yourself with others so that you know that even if they do, you will always have other people there for you.

Anxiety is a hard thing to overcome, but one of the huge things I see myself doing is replacing that person who walks out of my life. Its not the healthiest thing to do, nor the best. But its a human reaction.

I often ask myself this very question! Sometimes it's all about communication. Openly discuss your feelings in a vulnerable way and explain that even the gentlest encouragements and reassurance moves mountains in combatting those feelings. If you're both on the same page, it can ease your anxiety as well as help that other person understand your anxiety along your journey.

Accept the fact that things happen. People come and go. Not everyone is going to stay in your life forever. Don't let the fear of people leaving, stop you from living your life and meeting new people. Building new relationships is essential.
