Take time out to get away from the farm completely, in an environment where you don't have to think about it for at least a week (but preferably two to three weeks).
After this it can be good to reflect on where you are at, and think about what you want to achieve for yourself as a family.
From this point reset some goals and from this, plan for the future - but more on that next year.
Don't make any big decisions when you are tired and stressed!
In the interim enjoy the summer and have a great Christmas - you have certainly earned it.
