Paradox?

Can something that “winds you up” also “get you down”? Surely if one thing lifts you upwards and another thing pulls you downwards you end up in the same place? So if something ‘winds you up’ and ‘gets you down’ then it just leaves you feeling the same way as before you encountered it, doesn’t it?
I ask because Philippa says my constant moaning about work is winding her up and getting her down, so I said “In that case you must be feeling pretty neutral about it really. Good, I can keep doing it”
She hasn’t spoken to me since and looks like she might have been crying so I’m just wondering whether it might be my fault?
