Robwin:Even though your run was not particually unlucky, you somehow still felt that you had been unlucky due to the fact you had lost more $ that you had anticipated. And you are not alone...
I appreciate your willingness to share you data, since they did reveal a very common pattern for slot players. (and the majority of your play was on slots). The financial result is inevitable of course(long term) and you know it , but it is interested why you still feel that way.
The first games I played online was also video-slots and I felt the same way you did. (though I played at much smaller stake).
It seems most people do not understand what a 95% payout (or 5% house egde) game will do to your bankroll. It is an untameable beast that you gives you the illusion that you are in change, but in fact you are fooled. Slots are designed to deceit you and take you money - and they are damn good at it.
(reminds me of some women btw...)
Somehow the excitement with every spin combined with looking at the nice graphics, cool animations, sounds and frequent feature rounds gives players the feeling that they are in charge and they just need a few good features to win what they have lost. Hitting the feature does give some personal satisfaction that you did archive something, though you did nothing but press the spin-button over and over.. It does everything possible trick to make you stop thinking logically since your focus is everywhere else.
Instead you should be think:
HHmm. Pressing this spin button will instantly take 5% of by bet amount. 5% what does that mean compared to ie. 50% or 0.5% trying to figure out how bad 5% is. But trust me, it is very bad.
This monsterous house egde combing with the insane amount of spins you can make in a short time spam makes this the ultimative money sucking machine. Playing on a 50% house-egde state lottery game can actually be better in terms of EV. Because here you only make 1 bet for a whole week (and indeed give away 50% of your money). But this can be better than
applying a 5% house with small bets several thousand times during the week (number of spins).
The feature rounds is what makes the slot addictive to me. But in fact a
legendary feature round with a *1000 bet-size win, will often only give back
what you have lost during the last 4 hours. And we all know how often 1000*bet-size wins comes. (But I know how many hours it will last...)
Making the slot-analyzer really opened my eyes. I could do 10K spins on
Thunderstruck in 1 second. And I did it over and over. I also did lots of
life-time simulations to see the long aspect of slots. It draw a picture much more devastating than I had imagined. 100K spins and you were doomed.
This is from my memory, but I can check it again if anyone doubts it.
I did tens of thousands of life-time simulations(Thunderstruck) and the longest number of spins any simulation managed to stay in positive was 400K spins. I did continue each simulation for 10M spins, so this player did not get into positive again. And a very high percentage of them never ever managed to go into positive at all!
I believe I saved myself a nice amount of money making the analyzer. Sometimes people just have to see it themself to believe it. When ever I play Thunderstruck and hit the feature I know cry instead. Hitting the feature happens every in average every 143 spin and with 1$ bets this will cost you 7.5$.
So hitting the feature is just a reminder that happens regulary which tells you how much you have lost in average since last feature! 
The 5% house egde is an insult, but people are taking the bait anyway.
I also only play slots with 100% bonuses and I am not ashamed to admit it. I would be ashamed to admit I played slot without bonuses. Because then I would eigther be very stupid or an incurable addict that could not find enough bonuses to satisfy his needs.
It would be pretty darn stupid to do otherwise. Slots are not an easy and fun way to win money. It is a way (that I hope you find fun) to lose your money much faster than you anticipate.
In short: Know what you are dealing with. Slots are not quite what they look like.
