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

You can start by understanding that every person has positive and negative aspects; there is no one with solely positive or solely negative characteristics. That means that it's totally normal for you to not be perfect, and that it isn't a reason for your friends and family to abandon you. Then, you could write down the things you love about your self, and you think that your friends love them too. That will make you feel more confident, and grateful about the best assets of yourself.

Establish a strong ground of self appreciation first, you must realize how amazing and unique you are!

I feel like that feeling never goes away. Ways of coping with that situation are the best option I think.

Talk to them, think about the times you felt loved, try to think about something else and distract yourself.

Take a deep breath, and relax. It's never easy to sit with the feeling that everyone's going to leave you, but if you really think about it you know that the people close to you love you. Remember that.

Try communicating your insecurities to your loved ones. Explain how you have been feeling so that they can reassure you and help you realize that your feeling about being left is unmerited.

Understand the emotional connections you have with people. Frequently engage in conversation with your friends and family to understand the support they can give

Firstly stop thinking that!you know yourself and who you are and you know what qualities you have.never think someone is going to leave you ever.

That's quite a distressing thought, and it's okay to feel worried but they won't leave you, I'm sure it's just anxiety , your a good person :)

I don't think that there is a way to do that, however, you cannot assume that everyone is going to leave. Sometimes life is all about risks and you have to take them. You may end up having a lot of heartbreaks, but you may also end up finding the love of your life or your best friend. If you don't try you'll never know.
