Thank G-d, that stuff does still happen.
But as people get more and more disconnected from G-d, and more and more disconnected from that spark of G-d in themselves that's called the neshama, or soul, the more they're falling prey to all sorts of serious 'soul sicknesses'.
Rav Arush writes about soul sickness at length in many of his books, but particularly in the Garden of Healing. There, he spells it out very clearly that the further away a person gets from G-d, and from having emuna, the more soul-sick they'll be.
He defines 'soul-sickness' as all those negative emotions that we all have, like jealousy, angry, worry, arrogance etc; and explains that the more severe soul-sicknesses can show up as diagnoses for severe mental illnesses, including personality disorders.
Secular medicine has no cure for things like personality disorders and schizophrenia. Their best effort is to offer pills to try to drug away the worst symptoms, and if that doesn't work, their next big suggestion is to stick someone away in an institution for the rest of their lives.
Spiritually, there is a solution, and it's one that works wonders: learn more emuna. Rav Arush, and I'm sure others too, teach that the more emuna a person has, the more they try to see G-d in their lives, and to include Him, and to talk to Him, the more spiritually-healthy they will be.
When everyone starts following that advice, the world will be a peaceful, amazing, sane beautiful place to live in…but in the meantime, I thought I'd put together some energetic advice on how to deal with the crazy people who can suck all the life and joy out of you, if you're not careful.
The following things have worked for me, or for others, in some very difficult situations, enabling us to deal with 'negative people' without getting angry, sick or crazy themselves (no small achievement!)
Some of them sound weird, but don't knock it until you try it. None of these things can do you any harm, and they could help you tremendously.
Before and / or after dealing with someone you know is 'difficult', take a shower. Nothing washes away negativity like a bit of hot water.
2) Do the 'G-d is everywhere' exercise every morning (see below)
3) Carry your invisible umbrella - if you know in advance you're dealing with a difficult person who sucks you dry and exhausts, keep them out of your personal space as much as possible. Put up your 'invisible umbrella' to keep people at arm's length; if they're trying to hug you, stand to close to you, pat your arm etc, gently move away, so they're no closer to you than they would be if you were holding an umbrella. If you have to, don't be scared to police your invisible boundary forcefully. They'll get the message sooner or later.
4) Try to stand with them on your right-hand side - energetically, we absorb far more on the left-side, and are far more vulnerable from that direction.
5) Cross your arms - many of us do this automatically when we're around people who are a bit 'too much' for us. But energetically, it really does repel negative vibes.
6) Understand what you're dealing with: and that it's not your responsibility (or fault) if they're unhappy and negative. We don't have to 'fix' other people - and even if we want to, we can't! We are each responsible for our own outlook and happiness, so don't let a negative person make their problem, your problem. Keep your distance from them, emotionally, and try not to take their griping, unhappiness, rage fits and attempts to control and manipulate you personally. If despite all your efforts, you still get zapped with bad vibes, try the following:
7) 'Give it back to G-d' exercise - (see below). And then:
8) Take a bath in baking soda - I know this sounds mega-weird, but in practise is really does help a person feel more grounded, 'together' and cleaned-off from all the emotional 'ick'.
B'hatslacha, and I'm certainly looking forward to a time very soon when we won't need these exercises any more…
'G-d is everywhere' exercise
Rub your hands together, and shake them off.
Rub them together again, and then put them palms facing either side of your ears.
Bring your elbows together in front your face, and then cross your arms over each other, and sweep them out to the side.
Cross your arms over in front of you again, and again sweep out to the side. Do these criss-cross movements in front of you all the way down your body and legs, until you get to the floor.
Have in mind that G-d is protecting you, and keeping you cocooned off in His kindness and light.
When you reach the floor, put your two arms together, kind of like an elephant's trunk, and make sweeping figure 8 movements around your body, as you come back up from your legs to your head.
Take the 'Figure 8' movements up to past your head, then put your two arms together, backs of hands touching, above your head, and then bring them gently down to the sides of your body.
Imagine as you do this, that you are literally in a cocoon of Divine protection.
'Give it back to G-d' exercise
Rub your hands together and shake them off.
Bring your hands together in front of your chest, palms touching.
Zoom one hand up, palm up, to G-d, and zoom one hand down, palm down, as though kind of 'leaning' on the ground.
Now, switch sides - zoom the 'up' hand to the 'down' position, and vice-versa.
While you're doing this, have in mind that you are giving whatever you need to back to G-d, to take care of, while retaining whatever experience, learning or 'good' you need to keep hold of.
Do this another 2 times on both sides.
Then, bend over with your arms down in front of you, and take 2 deep breaths.
Now, slowly stand up, rolling your arms up your body as you do so. (Imagine you're rolling a beach ball up your body.)
Take your arms above your head, and bring them down to your sides.
Imagine, as you do this, that G-d is covering you in protective mantle of Divine light.
