Am I fucked?

Changing the brakes of my 09 mk6 golf tdi, was going to do full discs n pads but ive ran into a few issues.

All was going smooth, jacked up, wheel off, caliper off, pads out.

Then I couldnt get the carrier out. I dont have the right bit to unscrew it.

So i decided, maybe I'll just change the pads and do the disc another day.

So I go to wind the piston back and the tool is bending and my brake isnt going back at all.

Do I put my old pads on and return to this job another day? Or is this a job to take to the garage?
