No matter how hard life is, you have to stay positive. It sounds a challenging thing to do, but you do not have to make a big step right away, as a small change can make a difference.
If you are happy with your life right now, you can use the Relieved Face Emoji to indicate it 😌.
Moreover, the Relieved Face Emoji, which has a yellow face with raised eyebrows, closed eyes, and light smile, can mean that you are content and at peace right now. Use it to express your gratitude to someone, too 😌.
