Symptoms of a broken system etc... A bronze medal in the Olympics is well worth it in the eyes of someone who has dedicated his entire life (so far) to achieve this. It is short sighted, ignorant and extremely negligent, but this just mirrors societies attitude to COVID right now. On the other hand we elevate sports competition to matters of nationalistic pride, heroism, even politics and one of the greatest forms of vicarious achievements. An athlete at that level has already very little concern for their own health, likely taking PED of some form and pushing his body beyond it's limits. I find it difficult to be particularly mad at him. He did as everyone expected him to.
Gwondolier, Conspictor of Fartflames non-stop 35-attack-combo is a little much, but I think after the last three days I'm getting the hang of it.
Congratulations! 
It is genuinely amazing how entirely different people in different places of the world can have the exact same experience. I could have written that post almost word for word. Got my diagnosis last year (in my 30s) and it is exactly what you wrote: relief above all else. It ties my life story together. An invisible line steering towards chaos, that I have followed all my life.
Get some meds asap. They can be truly life-changing for us.
2 weeks ago CrowdStrike was just permanently taking up 30% of my CPU and kept my laptop running on maximum fan power. Apparently also due to a faulty update. Holy fuck, what is that company doing. And why is apparently everywhere?
Half my company is shut down. Laptops crash into blue screens after bios post and probably need to be wiped. Gotta love Microsoft. Exceptional customer service.
His head was glowing orange to indicate his weak spot.
Thank you. I remembered watching a video about this topic, but couldn't remember where. This was it.
"I'm just gonna shoot at the presidential candidate and see what happens" feels really wrong. He missed his head by a few centimetres. How is all of this even possible.
If you hit Donald Trump with any sniper rifle calibre from 150 m distance ANYWHERE on his body, the man's toast. He's a 80 year old jellybean, held together by his personal BigMac/Adrenochrome mix.
But the dude likely played too much COD or CS and simply got convinced that Trump has too much HP and you need to go for the headshot. Motherfucking 
The stock indices have reached new records after every single crash . Because capitalism must grow. Line must go up. Because if line go down, the whole promise of return of investment goes out of the window and the thing collapses. Any money you put in the market as a whole (ETFs), will be worth more in the future than it is now. But it has to be money that you don't need to rely on in the next 15-20 years, so it's exclusively for people who are rich already.
Everything else, like picking a single stock like those GameStop idiots, is just straight up gambling. Betting on horse racing is equally as productive.
Write that sentence down. Then read it again.
And then grab someone you trust and make them help you find a psychiatrist. It involves lists and calling and waiting and planning and appointments, aka all the things you are probably terrible at. So get help if possible.
Just a general word: ADHD is a dimensional disorder. Meaning, there isn't a single identifying symptom that differentiates ADHD from say, a more neurotypical person that is a bit disorganised. Everyone forgets shit, everyone is late once in a while and everyone fidgets when they are nervous.
So the question you have to ask yourself (and which will be part of the diagnosis): How often does that happen? Is this majorly impacting the direction your life is going and are you okay with it?
If the answers are "pretty much everyday" and "I would not be where I am, if I didn't behave like that and I feel like I can't do anything about it even though I want to", you have a pretty good indication.
Your wording and descriptions all sound very much like my (inattentive) ADHD to me.
