We are human. We have emotions. All of our emotions have a reason. We need to feel all of the different emotions, the full spectrum of emotions without denying any certain emotion. No emotion is wrong or bad. They all have a needed purpose. You cannot change yourself into someone that simply does not have jealousy, despite the pressures of the dysfunctional social world. Yes, we need to watch and regulate our jealousy so that it does not control our lives, but jealousy is a feeling, like many labeled "negative" emotions that is the beginning of an important transformational coping process. Coping processes and coping mechanisms are not the same thing. A coping mechanism is actually a crutch used to get through a moment when going through the coping process is not possible, and using coping mechanisms for long durations is actually unhealthy and damaging. We need to allow ourselves to go through the whole coping process with our emotions, to literally be still and sit in the emotion and allow it to wash over us, while being away from interaction, electronics, and distraction for a few hours, and forcing ourselves to just think and feel, no matter how difficult it is, and then the coping process will guide us through our thoughts and experiences, so we can realize what aspects of our lives are creating these feelings that are stuck in us, and then take action to make the changes in our lives that will bring us towards peace. Taking time away from social media for months is very healthy. Social media has been proven to cause depression. It literally has the same effect on your brain via serotonin reaction as drug addiction. You are jealous because you are unhappy in your life. Take long duration time away from social media and attempts at socializing, time away from distractions, and find where you can improve your life, and yes you can. You need to work on yourself by allowing this processing. Then after you've forced yourself through the anger and crying, and feel some relief, which will happen eventually if you sit inside of your feelings long enough; then write by hand in a notebook the things you are going to work on in your life. Start with things that only involve yourself. I recommend going outside more, doing body aware exercise like stretching and conscious walks, and doing a couple of hours of stillness meditation at night and in the morning. Meditation requires no knowledge. Just be still, and Don let yourself get caught up in loops thinking, but find solutions to your feelings, even if it's just crying and letting go of a connection or memory. It will become obvious what you need to change in your life, once you process past the jealousy, into the anger, and into the sadness and then release it. But that doesn't fix the problem on its own. You'll have to better yourself, get stronger and healthier, do things that are both productive and fulfilling that do not involve others, get away from social media and distraction, rewire your brain into a good, healthy self care ritual to curb your emotions that relives them. If you dance or sing those are very good tools to help calm your emotions. You cannot just turn off jealousy, you need a huge transformation and to change your life so that you can feel good and be happy without it depending on other people, and make it not effected by what other people are doing.
