I've got a serious dilemma...

No that first argument won't be the case... And how should I have used bankroll management? I think you should first build up a stable balance that can grow over some time and then manage it... I did withdraw some money when I made good profit.

that sounds like you don't know what bankroll management is. how do you decide what stakes you will play , how much you will buyin for how mny tables you'll play etc.

Ye ye, feel free to enlighten me, oh you God of BRM... I did use this already when playing and deciding what stakes I would play etc... I felt like my level was higher than the general player on the lower stakes so I decided to move up a bit but then I already collected a good bankroll with multiple buy-ins on the higher stakes. I'm such a BRM genius...

Do you want help or just to be a sarcastic dickhead to everyone trying to help you?

I'm also thinking, if poker is not for me, what do these pros have or can do what I could not? That might sound a bit arrogant, but I really believe I have all the skills to be a great player... I might not have nerves of steel, and I do have my flaws, but so does everyone, I think.

The answer is that they have and actively practise bankroll management. You couldn't even be bothered to google the phrase to find out about it instead you just assumed you knew what it meant and acted like a dickhead in your replies. Good luck , you're gonna need it with your attitude, I'm out.

Letting your feelings guide your decisions when it comes to choosing which stakes to play is almost always a mistake.

but then I already collected a good bankroll with multiple buy-ins on the higher stakes.

This is a more concrete way to choose your stakes, but it's not the whole story.
A good BRM strategy includes a plan for when to move up in stakes, as well as a plan for when to move back down.
Different people have different levels of stress associated with their total number of buy-ins for their BR. I recommend choosing move-up and move-down goals which minimize your own stress as to how much importance you put on winning or losing any single buy-in on an all-in play.

Winning or losing any single hand is literally nothing to concern yourself about. Whether or not you played the hand to the best of your ability is the concern. How the cards hit the table after each decision is irrelevant to whether or not you are making winning decisions. Choose your BRM strategy to acknowledge this fact. Choose it so that you can comfortably lose or win any given all-in hand.

Not for nothing, but if you are employing a robust BRM strategy, it is not evident from your posts. Your assertion that your decision to switch stakes was motivated by your feelings is a red flag which usually indicates an impulsive player who is not making well-reasoned decisions based on concrete data.

Try to maintain the humility about your current skills which motivated you to post in the first place. I know you admit to making mistakes and are comforted by the notion that everyone makes mistakes. This is true, but you would not have posted if you were not trying to be humble about your actual skills.
