I’m literally just a bitter bitch or something 😩

I used to have this best friend. Like best best friend attached at the hip type shit. We lived together for two years, went through school together graduated together, I taught her how to drive all that bs. I thought we was grown but when I got a bf it was the end of the world. He was soo nice to her and tried so hard cause he knew how important she was to me, and I was so nice to her bf even tho he was extremely rude and always told her I was “bad for her” even tho he didn’t know me at all. Well one day she moved out stole a lot of my stuff and that was that for our friendship. It was sad and sucked so bad like that was my only friend and it sucked losing her and the memories we had growing up are like fuckin tainted by her bullshit now. Then a few months pass and I find out she thinks we’re just “taking a break” from our friendship all while talking shit about me. I reached out and was like listen we ain’t in a relationship and you stole from me so plz get outta my life and leave me alone. That’s the last thing she did, she had her whole family cut me off except her little sister, and she continues to taunt me on random fake social media accounts. I’m happy with where my life is at but anytime I hear anything good is happening for her I get so mad. Like how could I be so bitter and I’m actually upset she’s getting engaged and got a new apartment. I just moved in with some friends and am so happy so why would I be upset she’s getting the same enjoyments out of life ugh like my anger for her is that fucking deep somehow. Idk I wish i could have my best friend back and I wish all the bs would stop and I need help on how to just not be so bitter. I’m so scared I’m putting these gross negative vibes out and the universe is gonna punish me. Idk like I was so happy knowing she had a shitty bf and staying in a shitty hotel sharing her shitty car she kept crashing.
