How are woman TTC supposed to "not try so hard"?

I have been at this now for over 5yrs and I am at my wits end w/ pregnant woman all around me, and family and co- workers asking why no kids??? How old are you? I am constantly being told....forget about babies..stop trying it'll happen. Obviously the people telling me this don't know the heartache or pion I have to become a mother! Anyone else experiencing these feelings! I am all stressed out and I do know my body wont respond well to that...how do we stay calm through this and reach our goal?
