Can WANT comes after NEED?

Felt so helpless sometimes on financial wise.
I know I should be contented of what I have compare to other kids that don't even own basic stuff.
Sometimes it really does make me question, why am I always in this poverty status when I need some help?
Why when I have those additional money to spend on something that I want, turned into the urge to spend something that I need?
Although NEED always comes before WANT, but can WANT comes before NEED for once? Or Occasionally?
I know it doesn't make any sense, ignore my rambling babbling =S
