Cs:Go Ranks

I was LEM, lost my uprank match (I was 100% sure it was it, 8 wins in row with good K/D, MVPs, Playstyle...).
Then I lost this one match and I stopped playing for 1 year because of.. idk I was just mad about it. xD
October 2016 I started again and was MGE, stopped and started again 2/3 weeks ago and I got ranked Gold 3 lel
