Congratulations, for what is important is you are reaching this empathy and consciousness now. You could try digging inside yourself (maybe therapy?) for what was behind your anger, and you could also try doing something to repair to those you wronged, but keep going, it might not be the easiest path but it's the wholesome one
Because of bandwagon effect. The more people use linux, then even more will. And itll get more support from software and hardware developers. And the world will be more free, safe, and not controlled by a big corp.
If it is a second hard drive... Probably the win bootloader is on the first still? Check bios boot options
Maybe its destiny telling you you can do it without windows
If you want something efficient and free of bullshit you probably first need to change your OS to a GNU/Linux distro
Beyond technicalities, there are social and political issues. Is it secure for the long term of humankind to use a browser which is one of the tentacles of one of the biggest conpanies in the world, which monopolizes the internet and relies on selling private people's data?
Vivaldi is a no go, it is proprietary software and also based in chromium. I've had similar thought process to yours and I am also using Floorp. Librewolf is great but too privacy hardened for the common lay user. These forks are cleaning the s*** out of firefox so no need to worry.
Being a linux user for 23 years and a linux promoter and installer for newbies, I don't agree with so many of your recommendations and priorities.
Asus went the bad way. Check out louis rossman vídeos about asus, héroes one of them. https://www.youtube.com/watch?v=NHQqKi9NcTs It is a company to be avoided. It went the non ethical way.
I've tried many things in this situations (seeing other girls, distracting with alcohol/drugs, etc) but they all just seem to alleviate the pain when they just throw it under the rug for a while.
For me, the best way to handle this has been to face my pain altogether. This pain does not come from this event. It is my own ancient pain that has been triggered by my now ex. Staying with the pain, listening to it, feeling it in your body and letting it be there is a transformative act.
I recommend listening to Pema Chödron's videos or books. Maybe "When things fall apart". I personally have been helped a lot by doing the "tonglen" meditation.
I used to contribute to google maps. I had the same vision you do. But then I learned about their dark way of stealing people's data. All your contributions to google maps are now property of google. You are giving away your efforts so one of the richest world companies becomes richer. And keep abusing their users. So now I use openstreetmap.org
Same for me. If you are interested in ease of use, instagram and x do the job AFAIK. But if you are interested in a resilient decentralized platform (and the future of humanity in a non dystopian world), bluesky is not one (although it pretends to be). So for me its mastodon and pixelfed all the way.
