I've spent too much money! ;_;

This is getting out of hand. It used to be I was able to keep track of how much money I spent on Riot points, but now I can only guess it is somewhere between 1500-2000 dollars. I don't know exactly how that measures up to some of you guys but for a broke University kid such as myself who is going to be in debt for the next 8-12 years anyway it is way too much. Yesterday when the snowdown shop opened, I got 70% off an already cheap mordekaiser skin, this may not seem like a big deal but when you consider that I already owned 2 Mordekaiser skins and only played him twice, it's kind of a problem. The probably biggest waste of my money is mystery gifts. Whenever I can, I mystery gift myself because ever since I've gotten Whistler Village Twitch that way, I've been dreaming of getting Pax TF through it. Because of this I've spent alot of money on skins I don't want or need. I have every Shyvanna skin and to make it worse, when I buy a skin on an impulse like deep-sea thresh (who I've played maybe three times) I get championship thresh in a mystery gift a few days later. I just need to stop, but I don't think I can unless I either find my main or get Pax TF and decide there is nothing better.

Oh yeah and in case you're wondering, I've only been playing League for about a year now
