The first two or three minutes is really painful but after that it's really quite easy… unfortunately I don't really want to start being depressed if that makes any sense… I have too many problems to deal with and it's easier if I'm entirely shut down, easier to avoid everything entirely and let it all go to hell… But if I were committed to optimal mental health… I would definitely be cold water swimming all the time…
Our town's swimming pool building whatever it's called had a cold pool with water that was only 4C. It was really nice.
I think I understand what you mean. Sometimes I think "If only I got this problem fixed, I could live" but then I remember that even if I got that problem fixed, I'd still have a million other problems that would force me to ctb sooner or later.
For example, my old dog died, I can't live without a dog, I want a new dog. I almost got a new dog, but then I recalled that I don't have enough money to take care of it. Then I thought about doing art commissions for money, but then I remembered that selling fan art is a grey business and people rarely buy original art (you'll get ten times more commissions if you say "I'll draw your favorite movie character for 50€ than if you say "I'll draw anything but fan art for 10€"). Then I thought what the hell, I can still earn money by selling prints or pins or tutorials or making a Patreon and posting youtube videos and twitch streams and getting donations. But then I remembered that in my country everything is illegal and taxed heavily. For example, Patreon (which is the main source of income for many artists/musicians/youtubers these days and has helped make many millionaires) is illegal in my country, because of course I live in North Korea #2.
Every time I find a solution to one problem it just ends up making more problems.
