I need some kind of emoji code or something for the following situations:

• "No is a perfectly acceptable and good answer to this question" for instance when asking if someone would like to do a thing etc
• "This does not need to be responded to immediately, take a look at it when you have time and mental space" usually when I'm asking questions about making plans ahead of time
• "This does not require a response from you at all" sometimes when I'm sending little messages of love and support to friends I know are already overwhelmed
