Yes, of course quantum physics is a theory, however, quantum particles do behave differently when observed, our minds can hold stuff in a quantum state, and atoms start to disappear when one gets closer to them. These have all been observed, and very well documented.
The whole point was exactly that we cannot see the point.
I think deeply, I always will. It's a part of who I am, a part of what makes me in unequally me. Do I think about this stuff all the time? of course not. Do I think about it enough? of course.
My experience tells me that proper boundaries can only be put in place when we innately love ourselves. Show me a person that abuses drugs, who is addicted to drugs, and I will show you a person who at the very core does not love themselves. Every. Single. One.
Because ultimately, if you love yourself fully, without restraint and with clarity, it changes everything.
