Coping with fertility issues

Tasha
I am 25 years old and after TTC for over a year I just found out that I can't conceive naturally. I feel like I have done everything right. I am healthy, exercise 6 times a week, healthy diet, take prenatals and folic acid, use fertility friendly lube, everything. I just never thought I would have to deal with this and am having a really hard time dealing with everything.  
My husband and I have an "infertility mock up" meeting on March 6th to discuss our options and the next step. I am just having a hard time processing and have no one in my support system who knows what I'm going through. Any advice for dealing with this news? I am so overwhelmed and upset. I just don't know what I should be doing.
