I'm willing to bet that what's transpiring is that your (physical) mind is habitually generating distored and inaccurate perceptions of what these individual's internal lives are really like (for them). Do you truly know what it's like to actually be living through all of their life circumstances and experiencing the emotions, habitual thought-forms, insecurities, and fears that these individuals actually experience? Generally speaking, It's very easy & common for individuals to make an effort to uphold a certain public image & persona because individuals naturally want to avoid acting and expressing themselves in ways which reveal their sensitivities, vulnerabilities, and insecurities while they are in the presence of others. Someone you are perceiving as having it 'better than you' may very well be struggling and suffering inside - just as much if not more than you. But you're not going to know about this unless they choose to reveal this to you. This is why external appearances can be so shallow at times and will not reveal the true depth & complexity of one's life experience & state of being.

What may actually be going on here is that your current state of being (marked by a lack of self-acceptance) is influencing your (physical) mind to engage in this habitual activity of comparing your 'life' to those of others and simply reinforcing the distorted perception that others must be experiencing something 'better' than what you are. From this understanding - the your (physical) mind activity and the reoccuring feelings of 'envy' should be viewed as simply a symptom of an underlying cause. The key is to uncover & increasingly shift your awareness to that underlying cause - which will be the heart of the matter. Eventually once you sufficiently conduct the necessary inner-work - the 'symptom' (the reoccuring feelings of envy and self-judgement) will cease to exist.... You can help yourself now by setting the intention and putting forth the effort to be increasingly 'mindful' (aware) of what is actually transpiring within you when these feelings of envy surface each time. Don't allow yourself to continually get lost the emotions and in the external circumstances you are reacting to... You have to remember to pause, catch yourself in the act - and then really try to make yourself aware of what is happening inside of you and why! The more you are able to actually watch & observe what your physical mind is doing when it's misbehaving and acting up - the more you will free yourself from its former debilitating influence on your state of being. It takes time, patience, and hard work - but there absolutely is a way out of this challenging (and temporary) condition you've been experiencing. You have to decide once you've had enough of feeling this way and that you are finally ready to explore a new direction and venture into previously uncharted territory...
