Work bullies...

I got bullied by a co-worker and I'm now traumatized to go back to work. It's taken a toll on me. Has anyone got to experienced it too? How did you cope up? Story time.. I was once liked and loved by people from work, not until i befriended this one co-worker. I vividly remember kasabay ko siya sa final interview. Idk kung red flag ba agad na FC siya after the interview like she messaged me borrowing money and i gently turned her down. Then came the first day of work. I was supposed to give her tasks and usually since mas higher ang position ko sknya and knowing first job niya, i treated her with warmth & gentleness, then wala pang half day ng work day she accused me of shouting daw sknya where everyone in the office was shocked kasi nga i always sit down at the corner working or it's either i'm on a field work. Then she spreads rumors about me each time my fiancé comes to the office to visit me or just send me random stuffs. Later on she confronted me that she's been diagnosed with borderline personality and so I forgave her and sabi ko ako na lang maging bigger person. Pero not once or twice naulit yung out of nowhere na pang aaway niya sa akin ang wrongful accusations that lead me to resigning from work kasi even the HR was not able to help me out despite of evidences. Rn I don't feel like going out anymore or befriending co-workers. 3 weeks na and hindi pa rin ako nag aapply ng work since then. Any advice please? 🥺
