I think you're looking for "svn switch":
-------
$ svn help switch
switch (sw): Update the working copy to a different URL.
usage: 1. switch URL[@PEGREV] [PATH]
       2. switch --relocate FROM TO [PATH...]

  1. Update the working copy to mirror a new URL within the repository.
     This behavior is similar to 'svn update', and is the way to
     move a working copy to a branch or tag within the same repository.
     If specified, PEGREV determines in which revision the target is first
     looked up.
...
-------

So, suppose /path/to/wc-from-trunk is your trunk working copy, you might try the following scenario:
$ svn copy <url>/trunk <url>/branches/my-branch
$ cp -r /path/to/wc-from-trunk /path/to/wc-my-branch
$ svn switch <url>/branches/my-branch /path/to/wc-my-branch

Just be careful with local modifications or unversioned files that you still had laying around in your trunk WC (they will be copied to your new branch WC, so you'd carry them with you). Keep an eye on the output of the svn switch command to see if everything goes smoothly ...
