Can it not be?

I'd stay in London but in a different part (Islington/Kensington/Hampstead/Hampstead Heath).

I don't think it's useful in any situation to treat people with pity, disabled people included.
Be compassionate, yes, but don't pity them - it's very humiliating and completely unnecessary.

I actually found someone here long ago who genuinely made me feel like we were soulmates.

I care to some extent. I mean, it's very important to me to treat everyone with respect (unless they give me a reason to do otherwise) and in the recent years, my interpersonal skills have improved a lot - I learnt how to come across as a friendly/approachable/extroverted person and I use these skills quite a lot because I'm well aware that this makes a huge difference in terms of my likability. But I also know that I can be very blunt, probably way more than what people are normally used to. If something bothers me, I won't stay quiet about it just to keep the peace. I prioritise honesty over being liked.

I've done that quite a lot tbh.

Nah. Caffeine is my only addiction and it's a relatively safe one so there's no way I'm quitting :D

That despite thinking that I was being sufficiently cautious and had a high tolerance, eating four edibles still gave me a horrendous panic attack and I don't think I'm gonna mess around with edibles for a long time to come.

I think the exact opposite - having children on an obviously overpopulated planet with thousands of scientists saying that we basically have no future and large parts of the Earth are going to become uninhabitable in the next 20-30 years…well, that's what real selfishness is to me.

Sadly, no, it's very unlikely.
