Gutted for you. I've had my 1.4 COD for 6 months now, first ever brand new car, i've had 3 other cars and never kerbed a wheel, until this one.
I've done the drivers side in the snow when I missed the drive entrance in my street, the bin lorry was in our street which is actually 2 way but has a narrow enough road to make it 1 way, so to go past it I went up the kerb via driveway cut down and missed, because of the snow making it invisible and put a small 20mm graze. I was furious, the other time I tried to avoid a pothole and bumped off the kerb, and it put a 50mm radius of very fine light scratches, which are very hard to notice, luckily they are on the edge of the alloy and not all the way up it. Everything has been laqcured, and I clean it up myself. I hardly notice them, especially the 20mm graze on the drivers side alloy, most of the time the wheel position hides it. I do notice the 50mm light scratches when washing...
You sound like me, takes pride in his car and cleans it well. I was so gutted when I did these, but now I don't really mind them. At the start I wanted to get it done, I live in Northampton and the nearest place that can fix Diamond Cut wheels is in Milton Keynes, and one guy on here used them and they fixed it well, but he noticed a small swirl under the lacquer and they apparently wouldn't do anything about it. I just told myself, for the sake of a small imperfection on a wheel (lets face it, wheels will never stay perfect) whats the point, because they might re do it and it might not be like new again anyway. I've settled to, if the salt gets in it and ruins the alloy I'll get them done then.
Just try to calm down, have a good think and base your decision on that. I know how you feel, it might sound silly but I got heart ache when I did both of mine, couldn't stop thinking about it and got quite unhappy for a good few hours until I started to tell myself it's not that bad.
Yours doesn't look that bad either, but it does if you see what I mean, it is actually bigger than mine and more noticeable because of those darker alloys show it up more. Shame
Have a good think!
