Your experience sounds a bit like mine, except more extreme. 
I am a beginner poker player - been playing / studying for about 6 months now. 
I was beating the lowest microstakes and decided to take a shot at some of the higher micro & low stake games because the rake was lower and the players seemed just as bad.
I took some bad beats and made some pretty awful bluffs into fish who can't fold.
Obviously if you think about it these are both good things - I was getting my money in good and my opponents were incredibly exploitable. 
But, I went on tilt, stopped thinking about my decisions and bled out half my roll with the worst possible result: I didn't learn anything from it.
Personally, I find the process oriented thinking required to play poker well quite difficult to execute as I am a results oriented person.
I have come to the realisation that it is unlikely I'll ever make as much money from poker as I will selling my skills to the job marketplace and am content playing to learn the game, only moving up when I am suitably rolled. Hypers have crazy variance and I find it tilting to lose over 30% of my roll in a short period. As such I prefer to err on the side of playing over rather than under rolled. 
Although I do not want to play poker for a living, I am determined to learn to beat this game and I have had some "a ha" moments through my short poker experience which have helped me improve my game:

• Found every decision you make in EV calculations - if you can't explain why the line you took maximises your EV against your opponents hand range & known tendencies then you're probably not thinking enough about your decisions. Working through the calculations is something the poker literature is pretty light on. Coffeeyay's math videos are a good starting point. 
• Play to learn the game rather than to win - if you have an edge over your opponents larger than the size of the rake, you will win money in the long run. Every lost pot is an opportunity to find new edges identify spots where you can win more or lose less. Failing to take these opportunities is insanity (doing the same thing over and over and expecting a different result). 
• Analyse your decisions and your opponents decisions - review your plays - could you have taken a different line to win more or lose less? Try to understand the lines your opponents take against you. This will improve your understanding of population tendencies for formulating your readless play and identify lines which you didn't think about before which may be more +EV. 
• Don't be in a rush to climb the stakes - personally I find it easier to make good decisions if the result won't emotionally affect me. For me this means preferring to play overrolled rather than underrolled. 
• Be happy when your opponent sucks out on you - if you're opponent sucked out on you, then by the definition of a suckout you got your money in while you were ahead. As the number of these situations approach infinite, you take all his money :)

Good luck with your goals.

Good luck Paralell. Really try to keep the urge of moving up to chase losses away. Don't even consider it an option. Just acknowledge that you're going to have a tough time on some days, even some weeks or perhaps even a bad month or two. You're new to the game, every good player goes through tough periods, it's impossible not to have rough stretches due to variance/not learning enough/playing bad/etc.
So acknowledge that it will happen, that you'll feel like crap during those streches, but realize that it won't be as bad as you think during that time. Just focus 100% on making good decisions, work hard, don't let yourself get tilted (and if you do, take a break from the session) and just make it NOT AN OPTION to move outside your bankroll.

Well average is quite stunning..I guess it is only concern with sales matter..
