To add what dk said, you can try these two servitors as well, which don’t require any skill to use, but can help with these things.
This one is straight up protection, especially for attacks, and physical safety.
This one can help you ward, banish and even manage your long term home/temple safety with you or teach you how to yourself.
I mention these because psychic attack can be very draining on your energy, and it may be easier to call servitors with static images than it is to discern if you connected with the right other entities or successfully warded yourself or any of that If your senses aren’t strong or they themselves are attacked.
I mean depending on what they are using and how they did it, I’ve even encountered some stupid good energy masking designed to look like other perpetrators causing the issues, or entities even, here lately.
Absolutely take extra precautions, I know some magicians even set up special wards/servitors and the like- for the computers and phones because of these things- you can’t be too safe unless your only giving into fear and paranoia which can make it worse- but extra protection can sometimes help alleviate that by helping your mind accept your safer now.
There’s a Raziel sigil @DarkestKnight channeled For similar too, I like to use it in conjunction with my other methods.
