10k swing, but in the bad way

Played a load yesterday, 5/10 10/20 25/50 plo. Hovered around winning $2k losing $2k all day and went into my evening session level. Setup my cake acc and was playing away there last night all so. Anyway up about $1,5 and was about to hit the hay(4a.m ish), when I got a tug on my line. I was sitting in the 10/20 on gpj on my own and some fish decided to give me their custom. Quickly stacked him for $2k when I got dealt aakk but only 1 suit, not to worry K hi flop. He leaves and another fish insto takes his place. Get $1k off him and I am now winning about $5k. He reloads for $2k and I am thinking lovely take this $2k and go to bed plus $7k. Anyway 40 mins later I have lost the $6k, $5k, $5k and a few $2k to shorties who have joined the table and am losin $5k for the day. At this stage the table has filled up and its a very fishy line up, but I just had to go to bed I was losing it mentally and feared tilt might not be soon off. Although I lost $5k I was very happy with how I played and managed not to tilt dispite losin 5 fairly big pots in a row never being less than 40% when the money went in and usually being a 60% or more favourite. I am playen at a higher level in the last few weeks and these kind of swings are common at this level. They still make me fill ill when they happen.
