Gyno recommended IVF...

I had an ectopic pregnancy a couple months ago and I ended up having my tube removed. Afterwards, I had an HSG test done that showed my other tube was blocked. I was coldly passed along to another doctor (fertility specialist) and the nurse said "he'll be handling all of your pregnancies from now on" and hung up. So, now I'm left with the only option of IVF. I'm scared and sad that I'm only 29 and cannot have anymore children. I have one from a previous marriage and I love him to death. I do want to make him a big brother though and its already getting too late. He'll be 7 in August. I want to have a baby with my current husband as he doesn't have any children. Any uplifting words? How is the IVF process? I need some optimistic and positive reassurance.
