If you can learn how to effectively communicate your needs without being overly demanding or emotional, adults are more likely to be supportive and helpful.
It helps to have an outline of what you want to say so you are sure you are communicating the full problem and what type of help you need.
One systematic structure to make sure you cover all the key information is the mnemonic, DEAR MAN. If you use the same structure each time, it will get easier and you will be more effective at communicating your needs over time.
(a) Describe the situation.
(b) Express how you feel about the situation.
(c) Assert what you want.
(d) Reinforce or express appreciation to the other person for respecting your request.
(e) Mindfulness of your goals or needs.
(f) Appear confident.
(g) Negotiate when necessary. Ask for alternatives. If you are confident in your needs, it is important to self-advocate.
