Hopefully you don’t take this the wrong way, but seems to me that what you’re missing in the puzzle is humility. I don’t know exactly what you’ve tried so far or experienced, but you seem to have shot everything down and painted yourself into a corner where you’re convinced nothing will work for you. There’s clearly a high level of frustration that is clouding your approach to any treatment or measures, and there’s a good chance it was there going in. Which of course means any measure you try will likely be predisposed and doomed to something short of real benefit. Self-fulfilling prophecies and all.So, is there something I'm missing in this puzzle or is it just a matter of getting over myself and moving on? I can deal with being unhappy personally. I just hate it for those around me. They don't deserve this version.
Where the humility comes in is to ask yourself whether you’ve actually, objectively put in substantial effort to explore the more common treatment approaches, and leave no stone unturned until you find the blend of measures that helps at all. That same blend may not help forever, and so you may need to keep searching and tweaking and evolving. As everyone has said and you already know, it’s a very individualized process and challenge.
Again, no offense and just as I’m perceiving this… but the mindset of “been there, bought the t-shirt” sounds dismissive in a way that makes me wonder what the level of commitment to that search has actually been.
A good example is the breathing or meditation you mention — that’s something that is based in hard medical science. If anyone approaches that in the right way and practices it in the right way, it has measurable benefits. Even for the 10 minutes you mention. It’s not going to be the same experience every time though, and your circumstances and mindset aren’t going to be in the right place for it to be super effective every time. Especially starting out. But the humility comes in yielding to the science and how long those types of practices have endured, and the vast numbers of people they’ve helped, and in sticking with it even on the days it feels like total bullshit to you. As the habit sets in and the practice gets cultivated, people feel the benefits more clearly. Sure it takes some time, but other than that you have nothing to lose.
But if someone thinks they already know all the answers and is convinced there are no answers, then that’s obviously not a great starting point to getting better. You gotta recognize that. Regardless of how tough it may be to flip that humility switch on, that’s what will ultimately be required to take steps in the right direction.
