Extreme surgery needed

Will someone please help me? I think I need to enter rehab.
My problem?
I started in a small way, ordering music and books from Amazon, then computers from Dell and Apple. For a long time I was happy and then we started this remodeling project and things have gotten out of control. First I bought a sink online, then I progressed to faucets, showers and accessories, including a toilet seat.
I thought I could manage my habit, after all it was just one bathroom, a finite project. Then I started buying for the second bathroom, one we had no plan to undertake in the foreseeable future. But it was so easy, things were cheaper and readily available online. Just a couple of clicks, totally painless. So I ordered a vanity, and another faucet and I can justify it because it's a small project that will be easy to complete.
And then the madness began. I was searching for a door knob to replace the hideous pink stone one in the girls bath when I came across something I've lusted after ever since we moved here. A bronze mailbox, contemporary in style that reflects the design of the house. But it wasn't in the budget until we re-tarmac the drive. (Ironically we missed out in the great mailbox vandalism episode that struck the village last May when most of out neighbors got a new mailbox courtesy of the idiot who smashed them with a bat and was caught by the village police. End of term madness, almost as expensive as remodeling).
Today though, I was having no luck with the door knobs but one little weblink and I found my object of desire. Instantly available, it was perfect; it even looks like our roof line. And two clicks later I had ordered the Da Vinci mailbox.
I'm sure I'm going to love it when it arrives, but right now I'm feeling a little sick. I will have to buy a new post and dig out the old one and concrete in a new one in a new position. More tasks and btw it's February and the ground is frozen. Crazy woman with bad credit card habit.
Plus I still haven't replaced this beauty.
Help, I need help, either the credit card or the internet will have to be cut off.
