It is painful to think of being bullied in the past. I didn't answer blows with blows, and I couldn't let it go, which seriously affected my life and I didn't want people to take advantage of it.

You are an introvert. What you said is not your fault. On the contrary, it shows that you are still a kind person because you didn't fight back. Not to say that not fighting back or resisting is cowardice. You can fight back, you can resist. You didn't do this because you have a conscience and kindness. As you said, if you were him, you would never bully or offend anyone. Let's just say that the old man said that suffering is a blessing, and this sentence is reasonable. You can try to communicate with people you hate. If not, you can find a place where no one is around and shout. In a word, you should not regard your kindness as cowardice.

If you can find people who bully you, ask them why they bullied you in the first place. If you can't find it, you should forget these unpleasant things as soon as possible. You're making trouble for yourself now.
