Now she is excoriating my character...again.

Sarek, probably an interaction ban is appropriate as suggested. I do have questions concerning that: does whomever race to the Karel article first get to be the only editor?. I see she just received an interaction ban with yet another user. She has stalked me to two other obscure articles,(Margaret Clark and John Tran), edit warred without repercussions, hence totally discouraging me from editing other articles in which I am interested. When I reported the obvious stalking, I received no relief.  You pointed out that she has accused me of edit warring alone. I have never been extended good faith, civility  or any other "pillars" from this editor. She constantly threatens me. She flagrantly violated the 3RR just yesterday with no repercussions to her personally. 
I made a lot of mistakes at first, apologized and moved on. I have studied this maze called Wiki, learned and grown a lot, yet she is still accusing me of the "same old, same old" from two years ago. (See Karel's talk page.) Seaphoto, FeralDruid and AFriedman and others, have been a tremendous help, even when they were upset with me, as I know you have been.  BlackKite was a big help but I understand he got disgusted and left. As a "newbie" I was viciously attacked and stayed away for several months.  Right now,  I cannot figure out many of the procedures for complaints i.e. 3RR, without some assistance, I tried tonight. I have taught at University, I was Valedictorian of my college class and am continually talked down to as if I were an idiot child.  I sincerely endeavor to write honestly, with NPOV and no weaselly or peacock remarks. I strive for the TRUTH.  I am asking for help here.
TMI, perhaps. I am deeply in mourning for my sister. While my little sister was dying, SRQ cruelly mocked me. (See my talk page, Feb.22.) My  sister died on the 24th. I know your Mom died around the same time, I am so very sorry for your pain, I am with you. If this is too much, I apologize. I just do not understand why this has been allowed to continue for almost two years.
In Good Faith   

In another vein, I suggest you read about narcississtic personality disorder, you might find it interesting.
