My only suggestion is to not try to handle all the stress and anxiety by yourself.
You need people to rely on, and this process is infuriating, emotional, anxiety-producing and generally crappy. If you know people who have gone through what you are going through, by all means turn to them! If you don't want them to ask for updates, tell them that! Say, "I really need someone to talk to but I can't handle giving updates on my procedures. If something happens worth sharing, I will definitely let you know."
Do not make yourself an island. It will only increase the stress that naturally comes with trouble conceiving. Rely on as many people as you possibly can so that you have a huge group backing you up! When you fall (and you will fall at times) there will always be someone there to pick you up.
Good luck and I hope this is a short journey for you!
