I think I may have a League gambling addiction..

I just did some math and realized I've spent almost $200 in the last 2 weeks, on RP points to buy Hextech chests. It started because I really wanted a particular unattainable league skin ( SKT T1 Zyra ) that you can only get from hextech chests. I have gotten a few decent random skins, but mostly boring ones I don't care about. I end up combining 3 and rerolling and most of the time I end up with a crappy skin I didn't want in the first place. Then, I buy more RP and do it all over again - there's a daily limit, I usually cycle through all the chests it will let me buy before I have a cooldown for all of them. I literally have no self control, I get more and more pissed the crappier skins I get, and I keep telling myself that I'll get a better skin drop from the next chest... Has anyone experienced this or know anyone that has?
