The distinction between the two lies basically within what the intended meaning is. Wanting something has to do more with the desire for something. The wanting of something is not a matter of life or death in grammatical terms. When someone or something is in want of something, there is no urgency. Interchanging want and need with each other without observing the intended meaning between the subjects changes everything or could result in miscommunication.
>I want to go to the bathroom vs. I need to go to the bathroom.
>I want to take my medicine vs. I need to take my medicine.
>I want to get out of this marriage vs. I need to get out of this marriage
>I want you to turn down the oven vs. I need you to turn down the oven.
>We want to change your loan repayments vs. we need to change your loan repayment.
>“Your boss wants you to get to work on time or she will fire you” vs. “your boss needs you to get to work on time or she will fire you.”
>“I want you to feed the baby according to the eating schedule the doctor put her on vs. I need you to feed the baby according to the eating schedule the doctor put her on”
The urgency of something changes depending on which of the two words is used. Careful attention must be taken in this.
