Frustration

We've been passively trying for months now, I haven't had a period since Christmas, but every time we decide to test it only leads to disappointment and depression.

I say passively because I tend to have high stress levels anyway, I'm genetically prone to panic attacks, so we're trying to avoid high stress in trying "actively". At this point though, I know it's not uncommon for it to take a decent amount of time, but I'm worried I simply can't. I don't now how much longer I can disappoint him, I hate seeing him get his hopes up just for them to be crushed by negative results. All we want is to start our family, yet we're terrified we never can...
