Unfortunately, I think the only advice that can be given is " stay determined. " You may want to keep track of the order of Sans's attack and develop strategies for those attacks.

Or you can spoil yourself (nah, must say– I dun suggest) and go read up on [Sans/In Battle] (which I will not fully link to).

Then again, I've never done a genocide route, so I may not be the best person to offer advice.
