Please don't pressure yourself. If you hear that voice in your head telling you to speed up and apologise to your fans, tell it to go suck a lemon.
Your agency belongs to you and your enjoyment of the craft and it can wait. We will wait, too.
I know exactly how burnout is... You feel pressure to produce, to give into other's expectations, to perform being a good person who keeps his promise...etc It whips you with shame and guilt. When it is time to rest and recharge you can't, because a nervous, almost uncontrollable, part of your psyche is still whipping you for relaxing instead of being productive.
You won't feel energized if you keep whipping yourself to work. All your energy is being spent hurting yourself. You do have time and energy, but currently it's being used against you. Nobody should apologise and be defensive in every single paragraph they write for a production update.
You're right to self sabotage and not put as much energy and time into RYT as you use to if it is ruining you. Trust your unconscious even if you think it's working against you in this. It's actually protecting you right now. Probably protecting your passion or agency... If you notice any pressure at all, any amount of forcing yourself to "act" for the other's sake (audience approval or whatever) that's how your unconscious puts the breaks on. Willpower won't be enough to recover from burnout. Perhaps you wrote RYT in the beginning just because you had words to dump. Go back to that, whatever it was. Tear down those high expectations if that's what you built as an excuse to turn what you viewed as 'trash' into 'gold'. Putting out 'trash' again is how you reclaim all that energy.
For low energy I'd also recommend changing up your dopamine intake. IDK if you have too much or too little, so I will ask it in an easy to understand way... Do you think you're jerking off too much or too little? You know what you have to do.
Since I also identify as a writer, I know what going through these periods are like. I only discovered this about 2 years ago, it helps, but it isn't a cure-all if you're severely burned out. Give it a try. Be present in what you are writing... Maybe a paragraph, maybe a chapter...etc Give a clear cut off period, maybe until you feel a sense of satisfaction. Remember the feeling. Then go edge yourself. Don't finish. Instead of wanting the bliss of the orgasm, want the sense of satisfaction you felt when you were writing. You might feel sexually frustrated for the first 5 mins but I find it restores TONS of energy for me and I am back to writing day and night again without feeling like I am performing for somebody else; the process becomes the enjoyment. Edging is the only part that demands willpower though. Abstaining from porn helps a lot during those sessions, even if it makes the session longer/boring; the only thing you want to think about the feeling of satisfaction when writing. And yeah, it sucks not being able to climax for a few days while needing to also edging yourself... But I find it is worth the trouble. It gets easier in terms of willpower and feeling the sexual energy turn into motivational energy that is 100% your own agency and passion... Freeing yourself from the whip of guilt/shame is exactly what you need if that's what you've been using that to motivate yourself to produce. This little method will help, but you also need to work on the cup you choose to fill.
In Kung Fu Panda 2, Shen was also trying to fill a cup he cannot fill. He felt that if he finally had his parent's love he will be whole/fixed/complete in some liberating or healing way. When he couldn't do that he thought conquering the whole world will heal or liberate him. Parents love... Owning wealth/land...etc these are arbitrary objects the psyche chose at random... The intense desire for healing is the illusion. The nonsense object you might be chasing... money, partner, fame...etc all promise to fill a hole, but they wont. The cup/hole is bottomless. Once you realize that, you will stop whipping yourself with guilt and shame. You were using those as energy to chase the object that promises to fill you. Once you realize you will always feel like you are missing something, and accept and grieve that, you will stop working yourself half to death because of the pressure.
Sorry for bringing weirdness into your comment section. I was worried because you're currently my fav writer who posts frequently and you were acting as if you owe us all an apology or something. You owe us nothing. We're just glad to stumble upon what you're doing. Nobody here means to work yourself into burnout, nor should you pressure yourself into that for our sakes, or for some promise of feeling like the fame/wealth/accomplishment will "fix" the hole you feel at the center of yourself.
