Surgery! 😕

So I have to have my gallbladder removed on July 1st and my surgeon told me I can't have sex from June 12th until after I follow up on July 14th. I'm nervous not only about the surgery, but also because my fiancé and I have sex all the time and now we have to go 32 days without it. He gets moody without sex and I'm scared that we're going to fight a lot. I just got my period so I'm "in the mood" and it gets worse if it doesn't get resolved. Any suggestions??
