I still don't have the courage to text him. What should I do?

I can understand that I really want to talk to him, but I dare not go to him. Even if I send a message, I will struggle for a long time. What if I send it to him if he ignores himself? I will find countless chats here to convince myself to talk to him. Sometimes I will giggle happily when I say a few words. You and I are very similar. You send him a joke, or send him a smiling face. He replied and began to chat with him.
