How do I get over feeling that everyone is going to leave me?

Well....no matter how it feels...not everyone truly does...even when we feel all alone I don't believe for a second the situation is hopeless.

Focus on why your valuable and why their life would be without you in it know your worth and why others need you

If I had a feeling that everyone was going to leave me, I would feel very sad and low in myself. This would mean my self esteem would lower anger and maybe a change in my behaviour

there are several things that you can do, including understanding why you feel the way that you do, encouraging yourself, and talking to your friends about your feelings.Your feelings are just as important as everyone else's, try why you think like that, understand the situation in all angles ,be realistic,encourage yourself with positivism , talking or sharing to your friends will help, meditation will help to calm you down, understand the situation will help to analyse, and to get past it , there are many other ways too..

Our brains are like computers, and they want to simplify our life for us. They take our past experiences and crunch them down into 1s and 0s and give us expectations. If most of our experiences, or even if the first experience, or even if one powerful experience, is negative then our brains can tell us all experiences in the future that are at all similar to it will also have the feelings associated with it. We can try to change our thinking by replacing those negative thoughts with positive expectations as soon as they occur to us, such as, "I don't know for a fact this person is going to leave me, so I am going to have fun while they are with me and just enjoy it!" Life is transitory and people change, yourself included. It is not fair to expect everything to be the same all the time, so we must be prepared for change, however we must also be willing to accept new things as they come openly: without judging them preemptively for betrayals they haven't yet commited.

This sounds really scary and difficult. I wonder if talking about this further in a safe supported place would help you to look a the reasons behind you feeling like this? Maybe it could support you to share this with other people that might be able to reassure you that your are important to them and have no plans to leave? If you think this might be useful why not take the first step and discuss this with a listener?

Learn to understand that not everyone will stay but the right people do, nothing or anyone last forever.

Just trust in the people around you. If they love you, they won't leave you. We can't trust in everybody but we can't not trust anybody either.

Some people are only there to pass through your life and leave a memory or lesson. Others will never leave.

You can get over feeling that everyone is going to leave you by looking at what you do have and being thankful for those who are there. Do not worry about what has not happened yet and might never happen.
