No, likely not you, other than you've yet to learn how to effectively remove toxic people + situations, from your life. It's very hard to do sometimes,
Especially when that toxic person (to you) is at work or family.

I've left jobs that were great, bc I couldn't avoid the TOXIC person/people there (still maddens me that was the only way I thought I needed/had to handle it)...
And as for my Mother, the most TOXIC person I know (to me and likely many others), it's been a lifelong goal to protect myself from her TOXIC effects, which at this point, I unfortunately probably never will be able to accomplish.

Example: Last time I saw her (I went to visit), back in January, and after what I thought (hours) with her, hoping her toxicity was in my mind more than her actions, she proved AGAIN SHE is and always be a toxic person - And they cause you much damage long after you've last seen them,
Which is why I call those types of people toxic, instead of just mean.
