Warm greetings @samantha57,
First off, it sounds like a really difficult situation- I am so sorry that this person who you trusted and had such a strong bond with abused your trust this way. It sounds like there is a lot to unpack with this situation- as a personal recommendation, if you haven’t already considered pursuing legal protections and potential prosecution for her crimes (because it sounds like a lot of what she has done is illegal), I would urge you to consider it 
Magickally, I agree that layering on protective spells is always a great idea 
For yourself, I would recommend working Protection Spells (that’s a link to the full collection- feel free to browse for any that call to you!) as well as carrying protective items- you might enchant jewelry, carry and cook with protective herbs, or use protective crystals 
For your home and loved ones within it, I would suggest doing additional protective work attached to the space and those who dwell within. You might consider working with a Protective Deity of the Home, making Home Protection Powder, or leaving protective sigils/symbols near doorways and windows 
Once protection is in place and you’ve got a net of magickal safety, you might choose to top if off with a Return to Sender Spell- a similar type of spell to the Reversal Spell Jar, but more directly reflective in my opinion. Anything she sends your way is going right back at her- it’s kind of a dual-purpose shield and sword spell, so to say 
Those who are experts in energy work and auras will probably know better than I do, but my best guess is that the ring of color is an aura (likely yours, as it is around you). As for the hands, perhaps it could be a guardian deity or angel reaching out to you?
Do you have a guardian spirit, angel, or deity you work with? If so, it could be them. If not, you might consider trying to reach out and connect with whatever entity it may be (keeping your protective measures securely in place, at least until you are sure they mean no harm).
Here’s a great tarot spread for reaching out: Who’s There? Identifying a Deity Through Tarot
Whatever you choose to do from here, I am wishing you all the best, @samantha57! Good luck and blessed be
