Sadly, it's over and you need to focus on moving on. She's made it clear that there's no getting back together with all the blocking and asking you to leave her alone. You can't talk someone into getting back with you, even if it would work, it's destined to fail eventually. I'm sorry to be so blunt, but you've got to move on.0

Your young, so take this as a learning experience.
1. "Begged and pleaded for her to come back " The worst thing you can ever do, also shows you have little self respect, and continually lowered your value in her eyes. In the future, just give them space, and let them know they can contact you if they change their mind its 50/50 they will.
2. "Keeps telling you to leave her alone " LISTEN to her !! She is communicating exactly what she wants.
I emphasise removing all reminders of her, and just continuing with your life0
