she's out of my life for good, guys, i'm not seeing her anywhere, threw out everything i had from her, blocked on all platforms and deleted all of her pics from pc and phone

it's been two weeks now and the situation isn't getting any better, one moment i'm feeling alright and happy, confident and looking forward to what i'm doing in the future, the next moment i'm down on my knees crying like a baby and gasping cuz i fucked up so much with her... i literally did everything opposed to the book...no need to go into details... these thoughts are not going anywhere, and they're making me miserable, unable to focus on my studies... I'd really appreciate any help to overcome this shit, it's really fucking me up and eating me alive
