Very deep meaning, love it! I am not entirely sure of the rhythm of this song, so I won't be able to help as much. I have a few suggestions, but you don't have to use them.
The third line, "that's how I just want to escape it" could be "that's how I want to hide it"
The fourth line, "I wish I could look at my past hold on to the good and throw the rest in the trash" could be "from all the things that brought me down I can't even fight it"
The next lines could be "just take a look at my past, tell me why I can't leave it"
"I just want to find that paradise of peace"
"Through all these tragic memories they keep on bringing pieces"
"That's how I want to leave it"
"That's how I wish to leave it"
