I found that B vitamins, ginko biloba & ginseng are a huge help in making me feel stronger & more in control so that I cannot be attacked. I've been attacked psychically for 2 years (first a vampire, then a neg). The last year & four months, always at night, every night. I'm actually getting a few nights a week where it's not able to attack me at all.
It's not enough to get the depression (from the attacks)under control, you have to feel confident that you cannot be attacked. The Ginseng & B vitamins help greatly with that.
Also, avoiding the place where the neg lives. I managed to switch around
my schedule so that I'm no longer forced to go by where it lives.
That made a significant improvement as well.
Am experimenting with more countermeasures & will report them soon.
