It's so easy to look in the mirror and point out your insecurities. But, instead of counting all the things you wish you could be, try counting all the things that you are. Make a list of your strengths, such as the things you are good at, the values that you hold, and the friends that you have. If you are having trouble brainstorming what your strengths are, ask a friend or family member what they think are your most positive traits. This is one of the hardest things for many of us to do, but it is a necessary step toward navigating your life. In many of today's societies that focus on the individual, we are encouraged to strive for success, and often we look for praise as the acknowledgment of that success. We take any criticism as a negative thing, so we shy away from seeing anything about ourselves that elicits that reaction. To try to be honest with yourself, imagine that you are observing yourself through a stranger's eyes. Ask yourself what that person thinks about you, and be as objective as possible based on the facts, rather than what you think about yourself. Remember that you can't fix it until you can admit there is a problem. You can view mistakes that you make as learning opportunities, as ways to get where you want to go in life. Have faith in yourself, realize only you can change you, only you can control your destiny.  Decide what is important to you and set your mind to it.  Remove self-doubt and have faith you can become what you envision. When you realize that mistakes are learning opportunities and that your reality isn't always fixed, you will be more likely to persist in the face of challenge, to persevere, and to grow in meaningful ways. Vent your feelings about your life to a friend or family member who cares for you and will give you the attention that you need. You may find that just by putting your thoughts out in the open that you realize that they are excessive or that your life isn't so bad after all. If you don't feel like just venting, try asking your friend or family member...

TL;DR in Indonesian:
Akui kekuatan Anda. Jujurlah kepada diri sendiri. Akui kesalahan Anda. Berbicaralah dengan seseorang yang Anda percayai. Carilah bantuan profesional.
