<human>: Condense the text into a few key points

It was never meant to be a long term relationship. Due to our age differences and as I got to know her I realized she had a serious drinking problem: two DUI's, court mandated ankle monitor to read her alcohol levels (that was later), and she's psychotic when she's drunk. While I was in the process of breaking up with her she found a lump in her breast and weeks later was diagnosed with breast cancer, shit. I tend to be codependent, I can admit that. there was no way I could leave her when she's going through all of this(son of a cancer survivor). I was honest about how felt about our relationship and we did a off and on relationship that involved tons of heart ache and remorse. She made it through surgery and didn't need chemo. Our back and forth continued throughout her recovery. Until finally two months ago we attended a party where she drank too much and had a psychotic episode and screamed that I was hitting her, if it wasn't for my neighbors who witnessed the whole thing I could have been arrested for domestic abuse. 

She tried to reestablish contact with me numerous times after that night I told her that we were bad together and we both needed help. I then blocked her number,  I filter her emails, and blocked her on Facebook. Since all of this happened I'm starting to notice that my friends are not speaking to me or reaching out. I celebrated my 35th birthday alone. It was depressing and still is. 

What should I do its a small city, everyone knows each other and she's somewhat of a local sweetheart(when she's sober)
<bot>: My functional alcoholic ex has turned my friends against me/I'm feeling isolated and she's everywhere, what should I do?
