Speaking of handling...

The animals sense fear/anxiety thing is honestly just a load of junk, so I wouldn't give any mind to it. The hand shaking should be a problem though I guess it could if she ever went into feeding mode. The shaking would resemble a rodent moving. You're fine, so don't let some non-sense they preach today bother you at all.

How can you be so sure? The vast majority of communication isn't verbal, and animals are far more attuned to body language than most humans are.

OP - Your snake isn't a machine. She will have behavioral nuances from day to day, just like any other animal. She'll get used to your shaking, if she hasn't already. I wouldn't worry at all.
