You probably aint gonna listen, but I'm gonna say this anyway.
Over time, two simple facts have been displayed:
1. Every now and then you do something positive, take some sort of positive step, and something good happens. After this you'll have a period where you're less frustrated and angry. You've already shown this happen multiple times now (wheras previously, you NEVER let it happen... that is progress). This, now, is the first of two options, the one that allows progress and improvement.
2. You can allow frustration to take over. You blame everyone else... accomplishing nothing... and you just post complaints about how the world is against you... accomplishing nothing. You make no changes, accept no responsibility, and only bad things happen. This is now the second of two options, the one that denies progress and improvement.
At this point you *must* choose one of those two options. This is not avoidable. After you do that, regardless of the result, this exact choice will present itself again. Again it will be unavoidable. This will keep happening. Over, and over, and over. No matter how much you may complain, no matter how you try to deflect the blame, or curse those around you, or make these "woe is me" topics, the first of the two options will always result in bad. The only way to get a good result is to choose the second option.
I must stress that you are not the only one who has to deal with this exact pair of choices, this exact loop. I've been through it myself, for so much longer than I want to think about. It wasnt about relationships, as I've zero interest in that, it was about other things. I chose option 1 over and over. Nothing useful happened until I started choosing option 2. My old loop finally broke. It was hard... it was *very* hard. Option 2 is always hard in some way. But still, it was the only way.
If I can break my own negative loop, even with just how far I'd fallen, you can break yours.
But until you choose that second option (many times, not just once... you cant do it only once and expect to magically get what you want, it doesnt work that way), I will stress: YOU WILL NOT GET WHAT YOU ARE AFTER.
That's all there is to it.
I would love to see you succeed. But I cant make it happen for you. YOU have to do it.
