Will I ever stop crying?

Jas
My girlfriend got hit by a car on April 19th 2017 and I was there with her but I didn't get hit by the car I cry myself to sleep almost every night thinking about her and I kind of feel guilty about it because she got hit by the car and it wasn't me and everybody in my family was like if it was me who got hit by the car I would have died but she can't live a normal life anymore she's going to have to do school online until another year goes by she's going to be afraid to go outside she's going to be afraid to come over my house I just don't want her to hate me and when I go to the hospital it hurts when I leave cuz it feels like I'm leaving her for good I just don't know what to do anymore
