I dont know if this warrants seeing a therapist which is why i am hesitant: Jealousy
Hello Jae,
I think it's good that you are able to recognize that this is not what you want for yourself; you realize this isn't healthy. Part of enjoying life is being at peace with yourself so you can truly be happy for others. There's a saying, "Jealousy is the child of insecurity"; what are some things that make you feel insecure? Do you suffer from low self-esteem? If so, what do you think contributed to that? What are you afraid will happen if your friends spend time together? True friends really support and encourage each other; so when you find yourself responding with negative feedback, stop yourself and ask "why am I doing this to a person I consider my friend".
Start being the person that highlights positive things about your friends genuinely, of course. Remember it takes nothing from you to be happy for others, to encourage them, compliment them or acknowledge that they have something you don't. You will always be you and honestly that's enough. There's no need to be possessive over your friends; it's great that they get along; they still value you for the person you are even when you're not there.
I will say this though, people do notice negativity; they notice when you're being possessive and likewise they notice when you're kind and thoughtful, really strive to be the latter. No one is out to get you or do you any harm. When you have thoughts like this, really think about what you've experienced that validates that thought /belief.
I will finish with this: think about the things that make you uniquely you and really focus on those things; they will bring you joy. You owe it to yourself to never compare yourself to others, you have to live your truth; you are not in competition with anyone, ever. Think about the life you want, think about your purpose and live your life in a way that brings people together; don't push people away, that's hurtful. Show yourself kindness. You can schedule an appointment if you'd like to discuss this further. :)
I really hope this helps. Have a good night. - Vonda
