Igno4

Hey! Sorry if this is the wrong place for this (I just bought the car a week or two ago), I'm pretty new to these forums!

First of all, thank you so much.
I was in a parking lot at target, and I was backing out, when a friend in the passenger seat screamed at me to stop. I'm only 16, and have been driving for a little over a month, so I mashed the accelerator instead of the brake. I ended up bending their bumper a bit (probably just a replacement), but I screwed up my back end pretty bad. I drive a 2001 Honda Civic, and the damage looks like I'll need a new bumper + body work and possibly a new trunk.
Here's some pictures of the damage: https://i.imgur.com/CCkTx.jpg https://i.imgur.com/xKOVA.jpg
Any idea what the total cost in damages (for my car) will be? Any help is extremely appreciated. Insurance is not involved, so I'll be paying for this out of pocket. Thank you very much!
