Ouch, sorry to hear about this problem.

Well, if you don't feel like replaying all levels, one option is to warp to E5M7 and give yourself some stuff via console commands (e.g. "give weapons", followed by "give ammo" and finally "give backpack" - this will give ammo but not max ammo, to keep things fair). You'll just have to turn on "sv_cheats" before starting a new game, so that it would allow you to use the "give" command.

Another option is to rush through the previous levels (if possible) and skip the secret level.

It's up to you :)
