I've read your posts and I sympathise with your struggle, most traders go through a similar process so you are not alone. I know it's extremely difficult but this is actually a perfectly "normal" process that most people absolutely need to get through in order to trade normally.
You already know that in order to find success in trading you need profitable strategies, smart money management and a strong mindset, it all needs to be in sync and aligned with each other. From what I gathered from your posts, this inner struggle that you are experiencing is because your current mindset is sadly nowhere near a trader's mindset, the further away it is the more difficult the struggle. But again, this is normal, we all have to do a lot of mental work to acquire that mindset. Profitable strategies and methods are useless to us if we don't possess the necessary mental skills in order to profit from those methods.
You seem like an extremely emotional person, this does not help your cause. Perhaps you should cut yourself some slack, if you get angry when you make a mistake then you risk losing what little emotional control you had in the first place. Everyone makes mistakes, regardless of skill level, the main difference is how we deal with those mistakes, the attitude towards mistakes alone can make all the difference in the world. You need to accept that you will make a lot of mistakes and you need both to learn from those mistakes and to learn how to let it go and carry on.
I think everyone can overcome such obstacles, but not everyone is willing to go that extra mile to do that. Some profitable traders have never fully developed a proper trader's mindset, but they can at least recognize when they've lost control over their emotions, so they just simply close the ladder and step away from the markets. Restraint and self-awareness are important mental skills that you absolutely need as a trader.
That being said, from my personal experience I think it's MUCH easier to adjust your mindset when you've already developed strong profitable methods, because your mindset is not fully tested compared to someone who has a huge variance in their results and has to make several trips to hell and back before he sees any progress. In other words, if your results are able to cover the occasional loss of emotional control then you should be perfectly fine, eventually after you iron out the remaining mental issues. But if your results are directly dependant on your emotional state of being then that obstacle is so much harder to overcome, if that makes sense.
You already admitted that you're one of those who don't want to go that extra mile, but if you're going to give it another go then surely it would be best if you changed something in your approach this time, otherwise you risk getting the same outcome yet again. It's so much easier to work if you have a structured plan in place, you can find some useful pointers in this post and thread
