I worked really hard, but as a result, everyone gave me the cold shoulder. I think I am a joke myself, and all my previous efforts were in vain.

Love yourself first, then others! We often feel sad or angry, because our sincere efforts are often not rewarded or even betrayed. The reason is that we can't get what we want, give all the beautiful things to others, but ignore our own psychological or physical needs, treat others blindly, and hope that others can treat ourselves well, but it often backfires. At this time, our inner needs are not met, but we have paid so much, and those uncomfortable and angry emotions will follow. What we can do is to love ourselves before loving others. People are selfish animals. Don't think there is anything wrong with this. We are not saints. When you pay attention to and meet your own needs, then pay attention to others. Even if you are treated unfairly, you won't feel sad and angry, because you no longer expect others to treat you equally. You have done what you should. What they do has nothing to do with you. Your own heart has already been satisfied by yourself. Love yourself, dear people!
