I am trying to figure out how to say "I don't know what I would do" in French. But, I have been getting two different answers as to how to say "I would do". I read that you're supposed to use the conditionnel mood when trying to express something like this. However, someone else told me that you're supposed to say "je voudrais faire" instead of "je ferais".
Je ferais = I would do
Je voudrais faire = I would like to do
Je ne sais pas ce que je ferais si mon chat tombait malade.
I don't know what I would do if my cat got sick.
It's very simple. In this case, the would do, a conditional in English is also the conditional in French.
Otherwise, /I would like to go up to Paris for the day/ would be: J'aimerais aller à Paris pour la journée or Je voudrais aller à Paris pour la journée.
Je ferais is when you will do something, and je voudrais faire is when you want to do something else.
