Why did my former coworker buy xmas presents for 2 of her coworkers?

When I first started at my last job, everyone talked to me but Carla. She didn’t wanna be my friend and never liked me right from the start. I can’t bear it, so I begged and tried to pay her $$$, which she turned down. They called corporate on me but luckily for me, all the higher-ups did was put me on a different shift from Carla. Still, I needed an anger outlet, so I treated other coworkers like shyt, esp the people Carla DID like. I basically verbally attacked them regularly. I got written up for that and then flicked off my boss for writing me up. Luckily, she didn’t see the finger. I also stared at Carla on my days off and got told to leave the building, which I did…1 hour later. But really, I just desperately want her to talk to me. Finally, I found out Carla added everyone on FB but me, so I screamed at my boss in front of customers. They suspended me 2 weeks. I returned to work to on-call hours and ostracism, so I quit 3 weeks later. I spent 13 months total on that job.

Thing is, Carla hurt me. I remember pleading w/ my boss on FB to make Carla like me. Also, whenever Carla snubbed me, I reported it to the boss, who said to let it go. (For instance, Carla won’t sit at my table, etc.) I also ripped buttons off Andrea’s coat bc Carla’s her friend and not mine (no one found out.) I just need everyone to like me. Carla used to hate Jane for a while until Jane accidentally made coffee wrong and burned ppl. Carla thought it was funny and they were firends. I purposely made coffee wrong, burned myslef and Carla hated me even more.

Recently, she bought xmas presents for 2 people at her work. How come she likes them and not me? Hell, she didn’t even accept my christmas present last year! I’m so glad I treated those 2 ppl like shyt while i worked there.
