Not because I’m having a hard time, but there are a lot of people around me that are. But something I have seen throughout my mission is that the Gospel really does bring a Never-ending Happiness (See, Mosiah 2:41) and that sadness is really but for a moment.
That true happiness comes from knowing that God knows better than us. That at the end of something bad the good stuff will always come next. Whether someone is gravely ill, or someone you love is rejecting you, just know that through the gospels truth and light you can know everything will be okay and maybe for that moment we are on the same level as Job or Paul or Joseph Smith or any other of the great prophets to walk this earth. Like them we are here to learn the patience that comes so that we can live in that eternal happiness knowing that through Christ we will become strong enough to support those things.
