Spending on what I NEED and What I DONT Need

I tend to spend money excessively and I starting to think I may have a problem. Ive always gotten everything that I wanted and I guess that's why I'm the way I am now. If I want something I just go out and buy it sometimes not even looking at price tags. But it seems that lately my spending has gotten out of control I my latest purchase tells it all. I was shopping online and it pooped into my head that I needed rain boots now keep in my mind I could have probably gotten a pair for maybe 50 dollars but it didn't end that way. I go to my favorite stores website which happens to be Saks and I see the most amazing rain boots and they were Gucci I knew I had to have them. It wasn't until after I paid for them that I realized the price 325 dollars plus shipping and handling. It always seems like after I make a expensive purchase I always ALWAYS feel buyers remorse. I didn't know what to do I could not tell my dad even though I was quite shore he was going to find out on my next months statement. I then realized that I could have used that money for things I really needed and that I need to learn how to spend my money better and that designer (which was very nice) wasn't always a good thing. Its something that I'm still working on to this day to stop being so stuck on material things and just live my life the way I need to live it.
