I found this on my sister laptop 1 week after her disappearance what does this mean?

Im 15 and my sister 21 she left unexpectedly she been acting different few days before. So she usually leaves and doesn’t come back until like a few days later without telling us. But a week and 3 days has passed n I found the on her laptop. I’m not sure what she means by this but I’m getting even more worried I want to know the meaning behind this…. and we def called the cops after the 5th day because she usually comes back. But I feel like I made a mistake. But please anyone does anyone know what this means.

“I’ve been running I’ve been running to get away from you. Don’t matter how long it takes I’ll keep running away try to keep running away runnin away from you. Tried to fight it broken silence don’t matter what I do. If I stop running you won’t comfort me lord what do I do. Peace in my mind oh please can you set me free. Tried to Rescue me from all pain in mind the thoughts in my mind is growing rapidly. Try to run away but you keep holding me back. So why don’t you set me free. All pain is gone but I’m not free. I always ask myself I always ask myself what use if I can’t help myself. Begging to myself begging to myself to stay with me. Stay with me please stay with me. I don’t wanna go but you’re telling me to go. So set me free. Please set me free”
