Its so hard trying to get over her💔

Me and my ex gf were talking a little cuz she started school today and I go the next day cuz we go too different schools, I wanted to see how her day was going and I was also still waiting for my best friend to respond to my messages about blocking my her because I wanted to move on. I find out she already has a new gf despite just getting out of a relationship, and once again I felt sick to my stomach and cried. Even though I "agreed" to stay being just friends im still so jealous of her being with other people it makes me want to vomit. My best friend finally respond and told me to do it but by then I already had. Before I finally blocked her I texted her "Bye". I already miss her so much but considering how fast this hoe can move on im sure she will have no problem forgetting about me which hurts to think about but im sure it's the truth.. Tomorrow is my first year of 10th grade and I will make it my own. Nothing is gonna hold me back anymore. Im in my healing era starting today.
