Bike fit / correct riding position

After spending months with a vague feeling of having my saddle too low, despite being very comfortable, I raised it a few mm. As I then felt too far forward on the nose I adjusted it back slightly. Still doesn't feel quite right...feels a bit chafe-y which wasn't previously an issue even on long distances.

What now? Drop the nose a bit? Put it back where it was?

Throw the bike away and start again. You've broken it.
