Answer:
Maybe some periods and commas? Not very sure where the sentences end but maybe it will look something like this:
I'm still here standing alone in fear despite what you said, I'm here. Time stands still wondering why I'm here. Past mistakes brought me here. I wish I could make up the time that we lost here because I'm still here. Lonely nights walking the past. We fight things that we said were real but unsaid it is looking back 13 years. Da mn, that's fast. All those years we lost but I'm still here. The past is the past. I wish I could rewind that. Take my hand and you'll see that I'm still here. I'm still here.
Hope this helps! If I made a sentence you didn't originally have, just edit it.
