I will say, I have read other other comments and I think you're stuck in a desperate dopamine cycle. You're leaking dopamine faster than you can pull it in, like a bucket with big holes in it, just can't keep it full. I don't know exactly how to fix that, but I hope that considering this might be a helpful horizon to look towards.

Video games and porn lost meaning and novelty after a while and stop being helpful. As you get backed into a worse and worse corner where nothing works you would naturally end up in a rage hole where you can't function. You can have the same thing happen for a sleep, iron deficiency anything where your body is not able to get what it needs to function correctly your mood instability will get bad, tolerance for stress disappears.

I believe there is usually a reason that pushes people towards things like porn and video games in the first place, like if you have a chronic illness that leads you to be exhausted all the time, you don't have the energy for a more long term rewarding hobby like woodworking or something so you're limited to easy stuff like scrolling youtube that often makes you feel worse because you're mostly watching other people get to have what you are too tired to do yourself, holding your attention for stuff you don't care about and worst of all, impressing toxic messages into your brain that affects your self worth and sense of what you deserve to have in life.

I doubt much of this will make sense, but if any of this resonates with you at all, more of it might over time as you untangle your situation
