I unwrapped everything automatically and it endend up being really bad for painting. How can I delete the unwrapping and start again?

You can start again and re-do the UV unwrap just by doing the unwrap command again. In edit mode press U and select any of the methods. The UVs will be redone with the new method and the old UVs will be discarded. The mapping methods are explained here.
There is one exception to the above and that is UV pinning. If any of the UV vertices are pinned (they are red), you need to unpin them first with Alt+P. Pinning prevents UV vertices to be re-done.
Deleting the UVs is another thing. One mesh can have multiple UV unwraps and you will find them in Mesh Properties:
You can delete any UV map completely with the - button.
If there is no UV map awailable, the unwrap operator U does create one automatically when unwrapping.
The steps are as follow.
- Enter Edit Mode.
- Select all faces ( A )
- Hit U select "reset"
That's all to it. Your UV should be reset to the default starting point.

1$\begingroup$ This doesn't get rid of the uv map, it just kinda stretches all the uv area, making things even more annoying to work with than when I screwed things up before. $\endgroup$– RamCommented May 25, 2017 at 0:46

$\begingroup$ @Ram It is the question and the answer resets the UV. I think you guys were looking for a solution for a different problem ... OP wanted to "RESET" to starting point. That's all this step is about. It does not magically give you a nicely layout UV which is pure lazy on your end. $\endgroup$ Commented Apr 23, 2018 at 6:45
If you want to have a clean slate on your UV map window as opposed to doing a RESET and having a placeholder UV instead, press space and search for "Remove UV Map".
In 2.8 in properties choose Object Data scroll down to uv maps you can delete your uv maps there as well.
In version 2.93, click UV Editing and in Object Mode, select Material Properties and remove the material by clicking the minus sign -
