Don't use being in a bad mood as an excuse to perfunctory life. The world will not change because of your anxiety.
It's really important to be an interesting person, so as not to embarrass others or yourself. It's just that everyone is happy.
There are many beautiful things waiting for you in the world, so don't complain and don't give up, so you should be gentle inside and work hard silently.
People always have to learn to grow by themselves, and pain is always the best growth agent.
No one will accompany you all your life. You should adapt to loneliness. No one will help you all your life, so you have to keep fighting.
