break ups suck ass, it's important to mourn the loss. This might not help you, but when i was broken up with, i told my self that i'm a boat. This boat is still, it's sat in the middle of the ocean (the unknown) and it's just bobbing up and down. It doesn't need to go anywhere, it doesn't need to know how it got there, it's just there. After time, you'll want to start getting some wind in the sails and aiming for land, and so one day, you'll start moving on.
I'm nearly 7 months from my break up and i still think about and of her everyday. It hurts but this is just the way i'm dealing with it. crying and journaling helped me!
