IVF ADVICE PLEASE!😰

Hi ladies, I just turned 39 this month, hubby is 40,, hubby and I are both fine, we have unexplained infertility. So after 14 months of TTC and 3 failed IUI's, my hubby and I have no choice but to move on to IVF☹️ (luckily my insurance covers IVF) the thing is, I'm terrified to go through the physical, mental and emotional toll of IVF and for it NOT to work, I think this would completely put me over the edge and completely destroy me!😰 any positive IVF stories or advice would be really appreciated! Please help!!!☹️😣😰
