You can't. Because it's impossible to describe how hard it was for me in words, you would have to experience it yourself.
When I say "burnout", I don't just mean mental burnout. I've even been in situations where I went completely broke, lived homeless, and much more sensitive details I can't talk about on a public forum.
Of course it doesn't have to be all life threatening to qualify as a "burnout". I've been through more moderate burnouts where I just couldn't keep up mentally. I started doubting humanity (I still haven't fully recovered from this and don't think I ever will).
But overall, these are things you can't just describe. Even if I did, people who've never been through one will never understand.
What I meant was I got to know more about how the world works, and the world is a messy place the more you know about it. So basically what i meant was the world let me down a little. It is impossible to "unknow" what you already know, so that's what i meant when i can't recover, which is a good thing (although some people may decide to take it negatively)
So in my case there have been no downside and only upsides. I regret 0% of the decisions I made and the "burnouts" have been just part of the experience. Just like how when you date someone and you go through all the fights and perils, and it feels like hell when you're living it, but in a couple of years it's all good memory (not talking about weird cases like an abusive partner)
Have you ever had brake fade in a car? It's like that, but inside your mind. Everything starts feeling mushy and mental processes don't get the results they used to.
