Talking it out does help. We have told our immediate family that we have had trouble conceiving and they've been great. I don't go into the details with most of them but just knowing they know it's not an easy road and are there as support goes a long way. I have two close friends I have told and they've been great too.
My RE has this on his website and it really resonated with me:
"Infertility changes you. It’s a time when you find yourself disconnecting from those you love the most, family and friends. Isolating and pulling away from the fertile world can feel better than remaining a part of “normal life”. It’s very common to want to be a part of everything but not want to engage in anything. And as the gap between you and the fertile world widens, it becomes harder to be around those who now seem to disappoint you at every turn with their inaccurate medical advice, offhand remarks, and insensitive responses to your grief. But it is at these moments you need to be connected to supportive, loving. and understanding people.
Given that the infertility journey can take months or even years, being isolated and withdrawn from others can lead to secondary problems of depression and marital distress. Chances are, those who care about you WANT to support you through this difficult time; they just don’t know how. Your challenge is to teach them how to be the best friend and loved one they can be to you right now. One thing that is certain-- if you do not reach out, you are certain not to receive any support."
