The rule is, if you are doing more work than you can afford to lose,
do the work in a branch and commit as often as you cannot afford to
lose your changes.

It is easy to create a branch and switch your working copy over to
that branch if you realise that your changes really want a branch...

svn info
# note the revision and the url
svn cp url_at_revision branch-url -m "oops I need a branch as my changes
are too big to lose and not ready for trunk"
svn sw branch-url
svn ci -m "check-pointing my set of big changes"

From then on you can just check-point your work to your branch

when you are ready to merge back to trunk, just follow the merge
instructions in the svn book (if you have svn 1.5 or newer on both the
server and client this merge will likely be trivial)

AFAIK, the unfortunate answer is no.

you should have created a branch and check-pointed your changes to
that branch... especially if your changes are really important to you

You might be able to re-code three weeks work in three days with your
mangled workspace.... but as you never committed your changes,
subversion has not kept them for you :-(

Get coding :-( and next time use a branch

Sorry to be the bearer of bad news
