Hi Rose.
The end doesn't have to be in sight. We only have to do one day at a time. When I start looking down the road, I get the same kind of agitation you're feeling. Sometimes we get thrown a curve ball and sometimes a flyball drops in our glove... but there's no way to know when that's going to happen, so there's no way to plan for it, and therefore, no use in worrying about it. While your emotions are running high, try just dealing with today.
Hugs,
Smoke
