Would like examples of what negative strength would appear like

[Kuhani]

I have a witch that uses the spell Blood Money to "pay" for material components of spells. Her strength is only 11, so I would like examples of what state she would be in after applying this strength damage in her swift action. Would she even be able to cast the main spell? Could she stand up still? It's perhaps just roleplay (which is actually very important in our games) but it could make a difference otherwise as well.

For the most part, it doesn't. Once you hit STR 0, you're paralyzed as it is. Negatives just makes it longer/harder to recover.

As long as the Witch doesn't hit 0 (and thus go unconscious) they should be fine. Mind you they may be heavily encumbered at that point.
