Opposite of Hope?

Okay this is going to be a short post, but last night I told ACU-lady (acupuncturist) that I was really stressed out because I really want this cycle to work, and I couldn't stop obsessing and worrying about getting my hopes up only to have them come crashing down if it doesn't work out.  She said "noooooooooooooo" you have to get your hopes up because the opposite of hope is fear.  Fear can weaken your immune system and just overall make things worse!  Yikes my Qi!!!!!!!!!

So what do you think?  Do you agree?  What is the opposite of hope?
