Pointers on where to start with self-defensive energy manipulation

[valkyris]

I would describe myself as someone who has historically been extremely sensitive to other people's energy, and also able to be manipulated quite easily. I'm more aware of it now, but I would feel better if I knew of some self-defensive energy manipulation tactics that only focus on your own energy, keeping it grounded while repelling others? I'm very much a beginner in all of this, so I would appreciate if anyone could give me some pointers/terms/things to read into.

I found out about visualizing your energy as sort of like, the shutter of a camera or a fidget spinner. Spin it inwards, shrinks your energy. Spin it outwards, projects it. That's about all I know.

Appreciations in advance

I got a lot from the book Vampire's way to self defense, which works with draining negative energy and transmuting it into your own.
There is a lot of shielding techniques as well.
Also take a look at any banishing ritual. Can be quite effective for managing your own energy field.
