Toxicity can show up in a lot of different ways. A strong form of toxicity is constant anger.
These people are irritable and will get upset at you for the smallest slight.

Recent research from the Department of Biological and Clinical Psychology at Friedrich
Schiller University in Germany found that exposure to stimuli that cause strong negative
emotions—the same kind of exposure you get when dealing with toxic people—caused subjects'
brains to have a massive stress response. Whether it's negativity, cruelty, the victim syndrome, or
just plain craziness, toxic people drive your brain into a stressed-out state that should be avoided
at all costs.

Complainers and negative people are bad news because they wallow in their problems and fail to
focus on solutions.

Cynical people may complain endlessly about their lives, never be satisfied with how you act
toward them. Fail to contribute anything positive and throw distrust and unnecessary negativity
towards others.

As strange as it sounds, sometimes people don't know what acceptable behavior is. Acceptable
behavior to one person can be unacceptable to another. Toxic people drive you crazy because
their behavior is so irrational. Make no mistake about it; their behavior truly goes against reason.
Dealing with toxic people is something we all have to confront in our lives at one point or
another.

They'll be completely lovely one day and the next you'll be wondering what you've done to upset
them. There often isn't anything obvious that will explain the change of attitude – you just know
something isn't right. They might be prickly, sad, cold, or cranky and when you ask if there's
something wrong, the answer will likely be 'nothing' – but they'll give you just enough to let you
know that there's something.
Toxic people figured out a long time ago that decent people will go to extraordinary lengths to
keep the people they care about happy. If your attempts to please aren't working or aren't lasting
for very long, maybe it's time to stop. Walk away and come back when the mood has shifted.
