This makes sense, thanks Maarten. To make sure I understand correctly, it is something to the effect of my indirect effect is positive and my direct effect is negative (both are significant). I cannot really talk about the proportion mediated though? If I didn't have my mediator in the model, it seems as if the total effect would be larger? Thanks for all of your clarifications.
