Afraid of sending messages to others, others don't reply, and they are always anxious in the process of waiting, thinking that others don't like themselves?

You are a little insecure. Others didn't reply immediately, maybe they really didn't look at their mobile phones. News does not mean that calling is more direct, and feedback is definitely lagging behind. Sometimes people forget because they can't answer right away, which is possible, not because they don't like you deliberately not to reply. Don't care too much about your place in others' hearts. What you may care about may be fleeting in others. I want to let go.
