How can I eliminate this sudden overwhelming desire??

I have noticed a new, overwhelming desire to start a new collection, I won't mention what it is, it's nothing bad, in fact to some it would seem very trivial, even childish... it's a nostalgia hobby... but I am having a hard time moving away from it.

The past week or so I registered on the forum for people who collect these, and I have mapped out all the items from the list which I'm going to buy, each of which will cost $100-$200 with the rare ones going for anywhere up to $1,000, even those I put on my list to buy.

It is so irrational, I have an addictive personality, but in this case I really want to put my foot down and say no to collecting this, because it would take all my money away for months. I'm already in debt for $2,000 from a hobby I desired earlier this year. At the time that too was overwhelming, but now that I want *this*, that old hobby I couldn't care less about.

It's weird, I cycle regularly through my 3-4 collections each year, the hunger always comes back. It is a problem for me, today I bid on a few items to start the collection... but I forced myself to cancel the bids.

I've had this problem since I was a teenager, looking back at old diary entries... I know it all too well. You would be freaked out if you knew how deeply it occupies my mind, it pretty much occupies my mind 80 % of my waking day. Now that I'm saying that it is freaking me out.

Don't want to write too much more but one important thing is, the other night I was meditating and thought about not just these items, but other items I collect. When I set them in my mind, suddenly they took on a new dimension in my mind. The objects were just objects, but contained my essence. It was as if I had placed myself on these objects and grabbed those pieces of myself, and dragged them toward me. It made so much sense... why can't I see that I AM me, and don't need to keep bringing all these things that I attach myself to, toward myself. It's like expanding into a giant blob and getting bigger and bigger. Anyone experience anything similar and can help me learn / deal with this?
