Therapy would probably help.

That's a doomer by definition.

make some fucking noise

Change the things you can change. I'm sure you can change more things than you think.

I don't know how you can afford rent or food. In my country there is a social safety net where you will be provided housing and food if you can't afford it. If you don't have that, try reducing costs somehow, move to lower cost of living, look for a shittier place with less rent, idk as I don't know the reality of your situation. If you're from the US, I thought you do have at least limited social safety net?

Traveling is overrated, at least overseas. If you have any way to get around at all, traveling locally can scratch that itch. Also video games do indeed scratch the travel itch.

Making real friends and finding a life partner, both of those things are possible for anyone regardless of circumstances. I don't know why you think you can't do it, but I'm pretty sure the reason is just in your head, so something you can change.

Water becoming a luxury and never retiring does not affect you yet, all future things don't, i.e. it should be irrelevant for your happiness right now. While it is often a good idea to plan for the future, you can leave some things, like the world ending or similar, for future you to deal with and just actually not care about it right now. It's actually your decision to choose to feel bad right now about future things, I assure you, you can choose to not feel bad about them.

You're not crazy. Our future on this world is fucked, I can't deny that. Only thing I would say is that getting high all the time is nice in some ways but in other ways it sucks and is even worse than being abstinent, because you'll cause yourself more problems that you'll be forced to deal with until it's all over, and who knows how long that's going to take?

Have you considered joining a cult?

I don't do drugs except the occasional social alcohol consume. Drugs are a cancer, yes, they feel good, but thinking about the amount of people who die and suffer for them to exist, just hits me too hard. It's different if you can get them legally, but almost all drugs are illegal in my country. Right now, there's nothing to keep me going except for my life partner and my cats, but health and finding a good job is becoming harder at my age. Enjoy life as long and as much as you can, even doing drugs, but try to keep yourself sober once in a whole too. Do this, look for another way to enjoy life. If you are young, look for your older family members, they probably miss you.

Environment decay (aka climate change) is gonna force all of us into pockets of extremism where we start killing each other. unless you're the brave bastard doing a one man miracle decapitation strike that changes the system, Start building community now, lest you be caught alone when the flood comes to your valley on earth.

Get a better job and out of the city.
