I have been harassed at work mentally and now I want to leave without serving notice period

Hello, I have been working in this organization from past 1 year, I have been a good employee and my KRA have been met and I have been a top performer, my supervisor started to like me after I joined while I pushed her away, i don't want to date yet she forced me in start and in the end we started dating, my supervisor always used me to get the work done and I also did it, but she started showing unprofessional behaviour at work and which caused many arguements at work and spoiled decorum, i always used to point out unethical work done by others but that was always overlooked and instead of taking action they forced me to correct that work which i did, they promissed me recognition but i never got it, they showed favourism with other employees and said everything is happening because of my behavior at work, i always argued them about unethical work and abusive environment she just said it is corporate world and we have to endure it otherwise i can leave, now i got a abusive manager who litrally abuses us at work and in presence of my supervisor my manager abused me multiple times but my supervisor never intervened and stated this is part of job, when i reported to senior they all became against me and started treating me unfairly at work, they have influence all over office so even if i changed team they made things difficult for me, i have an on and off relationship with my supervisor at work and they still support unethical work and they never take action on the users but if i bring it forward they are ready to fight me all the way to prove me wrong, two days ago i just came back home and i quit the job and now i said to HR and VP that i do not want to continue my work, i briefly explained them that it is due to unappreciated behavior and always looking down on me and i am not happy at work but they somehow made me admit that i have been harassed and abused they saying it is because of me because i got involved and my supervisor said if i filed an complaint she will lie to the HR and investigational committee, my manager is a abusive person and all he wants is to abuse and wants us to accept that abuse with a smile and these are the things they are now using against me that i was always smiling and never came forward to file complaints but i knew if i did they will make my life hell at work, i get treated in a unwelcome way despite being a good performer and now they are even willing to fabricate data in such a way that it will make me look bad, all i want is just to leave instantly without serving my notice period and i want my experience letter, please advise what should i do, i don't want to initiate all this to have bad blood or leave in bad faith but they aren't leaving me with any other option, i am really feeling depressed.
