No, not everything is lost. In most cases the repair function can correct such errors. And if it does not, there still are some other ways to fix a broken table. However, you might want to try to create a dump of your database first. You can do this in phpMyAdmin using the "export" feature. If this works, you could at least return to the (damaged) state which you have now. (Otherwise things would become harder; you could try to copy the actual files, in which MySQL saves your database, if you have according access to the server.)

Then try the repair and see, if it solves your problem.
