You need to improve your perspective on some things. Realize that downswings are not a curse, but actually an opportunity - an opportunity to differentiate yourself from your opponents, and therefore an opportunity to make money.
In the eightfold path to poker enlightenment that you said you started watching, Tommy Angelo talks about "recipricality," which basically means that in poker money only changes hands when Player A plays a spot differently from how Player B plays it or would have played it.
Well, this applies on a larger scale too. Mathematically, EVERYONE will go through bad runs of cards, downswings - they are necessary and mathematically inevitable. So handling the downswing better than your opponents handle downswings (or would have handled the same level of downswing you are experiencing) is actually an opportunity to make money through recipricality.
This is pretty much a long-winded way of saying what Phil Galfond already said, which was something along the lines of, "How you handle downswings will define you as a poker player."
Also, reframe downswings from being a curse to being a blessing. They not only make most people evaluate their strategic game more critically than they would evaluate it when they are winning (and therefore cause them to fix leaks and improve their game), but they also make you "tougher," more desensitized to future *inevitable* swings that are less severe than your current one. They are a challenge. If you pull out of it, you will be a better poker player for having gone through it and made it out alive. And being a better poker player means making more money. Being a poker player is a marathon, so stop treating it like a sprint.
I know how you feel, I lost for a month straight at live 1/2 in June, lost $2k on the month, but kept my head together as best I could, took this perspective, posted some of my bigger hands, talked about and thought about most of my significant hands, corrected some mistakes I was making, and I eventually went on a heater and made $3300 back in 8 sessions of this month.
Right now, you are cursing your downswing, but you have no idea whether or not it will actually end up being the best thing that could have happened to you at this point in your poker career. So instead, Amor fati, love your fate. Love your downswing.
