Well, you can always heave-to!

A sailing manouevre which I didn't hear mentioning so far in this discussion. Very normal in heavy weather yachtsailing.

Try next time in 25+ kts after your first run outside, to jibe. Because at that time your are anyway full of adrenaline and all your muscles are tensioned and you are at the top of your nerves. So a jibe in heavy wind seems not too much to add to all your misery at that moment. Take your time when running the cat full ahead of the wind. Take care of the boom and try to slow down the travellercar. Turn into the wind.

And then...........do nothing. Leave the jib on the wrong side and let the main completely free open, let the tiller go. You will be amazed with the repose and the silentness of that situation. You are in heavy wind but everything is quiet; cat is moving slowly windwards. All is in control. Sails are not slapping. You can stand up, walk over your tramp, do a little dance, sew the jib if you want. And rest!

Then start thinking of how to spill a little more wind when sailing again. On your way back from the run; if you are really out of control, let the jib simply on the wrong side. By this little trick you can manage another 10 kts extra.
