I've used the plastic dunlop fingers picks - the metal ones are for lap steel aren't they?

The plastic ones were OK I guess, not the same obviously but you'll probably not get any better. When I used to play classical, I used to use clear nail varnish on my right hand finger nails to stop them breaking - works well.... maybe try that once you've grown it back...

In your position, I'd probably just do as best as I could without....
