Step 1: Think back to a social scene in which other people are very close and make you feel neglected/excluded. Think back to your feelings and thoughts in that scene and write them down very carefully.
For example, "when I saw my best friend and his other friend laughing happily, I felt as if I was not his best friend." I am particularly frustrated and heartbroken, because I really hope that I am the only one for him. I am very angry with him, because when he is with others, I feel that I am ignored and I am not that important. " I hope I am the most important person to him, no matter who I compare with. "
Step 2: Think about how your instinctive reaction will be in this situation. Are you sad and then you quit playing with them? Or are you angry and want to separate them, so you often interrupt them? This is just an example I gave. Please write down your own instinctive reaction in this situation.
If your instinctive reaction is to retreat, then I think you can express your true feelings in real scenes-you can tell them that I feel neglected by you and I don't think I'm that important to you. I think if you can express these feelings to your partner, they may think that you value him very much and you need him very much. Maybe they will pay attention to your feelings and invite you to join us.
3. If your instinctive reaction is to interrupt, interrupt, or other behaviors that are easily offensive to others, you may need to see your true feelings behind these behaviors, because these behaviors may be defensive, and our true feelings may be very hurt and fragile. We may need to adjust our response to reduce this aggressive behavior.
If your instinctive reaction is that you want to be better to attract others' attention, then you attribute the reason to that you are not good enough, which may make you less and less confident. In this case, you may need to stop, don't blame yourself, and ask yourself. Not because you are not good enough, but because you are sensitive to such a scene. Please believe in yourself and accept yourself, and you will naturally attract people who like you.
5. If your feeling of exclusion is very strong and traumatic, which seriously affects your social interaction or intimate relationship, then I suggest you seek professional help from a psychological counselor and explore the development of your ternary relationship. This may make your life clear and orderly, instead of being deeply influenced by things you didn't know in the past.
Above, blessing.
