If the people around you are negative and judgmental, this may make it difficult for you to accept yourself.   Seek people in your life who are supportive. Seek people who appear to be okay with themselves. Minimize the time you spend with people who complain constantly or instigate unnecessary drama. Building a network of supportive people is essential to being okay with yourself. This could be a more formal network, like a literal support group led by a therapist, or a more informal gathering of friends. By empathizing with others, you also improve your ability to empathize with yourself.  Attend a meeting or organize a gathering where your friends can come together and receive support. Do this at least once a month. Scientists have proven that not only are we happier when we are nice to others, but we actually live longer! Being nice to others can help you be okay with being you. Make an effort to do something nice for others without expecting anything in return, and soon you'll be more okay with you.  Compliment the cashier's jacket. Give up your seat on the bus. Volunteer your time at a soup kitchen. Kind gestures can be small or large. Anytime you feel self-doubt creeping in, change gears and focus on gratitude instead. List five things you are grateful for in that moment. Take a moment to really pay attention on each one: how does it feel to have that in your life?  Think about a physical attribute that you like. Do you have great hair? Think about an aspect of your personality. Are you good at school? Think about a person in your life. Are you close with your mom? When we are not okay with ourselves, we are often not okay with others. This equation works both ways. If you let go of judgment and try to accept others, you will soon start accepting yourself. If you find yourself making an assessment of the actions, choices, or identity markers of someone else, just let it go. Remind yourself that it's not your concern.
