Neighbor has been obsessed with me for years

Not sure what kind of advice I’m looking for, I (F33) just need to vent this because suppressing this has caused my autoimmune disease to flare really bad.

A woman in my neighborhood is having a one sided beef with me. It all started 9 years ago. She’s a neighbor of my mom but my age, we used to have just small talk, but she added me on Facebook and started messaging, inviting me for a drink and go somewhere. She really wanted to be my “friend” but I found her creepy at some point because I noticed that she was copying me. Same hair color, same make up, same car. She replaced and bought everything new. Then she made up she had the same auto immune disease as me, and when I got pregnant with my first daughter she also got pregnant. Out of nowhere she started ignoring me, at first I was confused because I genuinely never spoken ill about her even though she was being off but I never confronted her either because I didn’t mind.

8 years later my daughter and her daughter are going to the same school. It’s where I noticed she spread gossip about me to other parents. She’s staring at me and trying to get a reaction out of me. And then one day my daughter got out of school crying that her daughter called my daughter ugly and stupid because her mom said so. Mind you, a ADULT told her 6 year old daughter to bully my child because she has something against me. I still never confronted her because I didn’t took the bait, instead I went to the school and told them everything she has done over the years and the bullying never happened again and I still feel so grateful that the school picked it up so well and did something about it right away. The reason I never confronted her is because at this point I started to feel like she is not really right in her head and she was setting me up for god knows what she told other parents.

However, she is still obsessing over me. Always staring, always looking. Lately her husband is doing the same thing. I try to mind my business and just pick up my child from school and go home. And even though I made the right decisions by not taking her bait because who knows what she been gossiping about, lately I start to feel bad about it. I fantasize beating her up real bad for thinking she could get to me through my child. I fantasize about dragging her face along the streets for harassing me and bad mouthing me for all these years for no reason at all. I have a lot of suppressed anger and stress and lately my face is flaring really bad.

She’s quiet now, she’s not doing anything anymore. I ignore her, but still it’s flaring up. Moving isn’t an option and I’m not willing to move for someone who has a one sided beef with me but at the same time I’m also creeped out by her behavior and obsession. Has anyone had a similar story?
