Hi,
Some of your questions are quite interesting. Buddhism also serves the “cause of life” but a weighted one…try to find the time to practice formal sessions every day.
Formal sessions will put you in the right track. I got a “formal session scheme” from @Tobias not so long ago but it might not be adapted to you.
By the way : anxiety it’s a form of greed linked to some kind of dispersal in your case. This is not to judge you, just trying to help.
