I am so sorry. I was once where you are now.
It looks like the procedure for installing TAILS from Windows is identical:
https://tails.boum.org/install/win/index.en.html
and I cannot recommend non-free software on this forum, but if you type
"create bootable USB stick from windows" into your search engine, it will
take you to a tutorial at ubuntu.com, which is upstream to Trisquel.
Back in my day, it was CDs, not USB sticks, but running live gave me the
confidence to take the next step.
I seem to be the exception to the rule, but there was also a project called
GNUWin II that helped me lose Windows (XP and 98 back then so nowhere near as
toxic and malicious as what you're running) by becoming familiar with many
GNU programs, such as the precursor of LibreOffice, The Gimp (image editor
that replaces photoshop), audacity (sound editor), etc.
If you have the time, you could probably still find some windows ports of GNU
programs for motivation and to do what you can to minimize your use of third
party malware.
Keep asking questions. You are very brave to begin this journey and I am
excited for you.
As one of my mentors used to say back in the day, it's hard to believe it's
been 13 years already, welcome to the revolution!
