You're fine. If you MUST spend that money, put it towards DOING something rather than acquiring a thing. Maybe put it towards night school, or online courses. Or, craziest of crazy ideas, sock it away in the bank or your sock drawer.
Invest in photography then. Buy a brand new DSLR with decent lens or one of the new hot mirrorless micro four thirds.
That and a masterful course on photography. Stay cheap with the hardware until you know what you want.
If you find yourself running out of battery power, an extra powerpack can come in handy. I ordered one earlier from newtrent.com this year and use it a lot more than I thought I would. Lots more other manufacturers too if you do a quick search.
