Helen, this is the first time you have done this - there are bound to be some problems, and after four hours of sorting fences even my (usually saint of a) husband can be a bit difficult, shall we say.... However usually a good meal (pork roast!) and apple pie sort the issue and we try and chat about how to do it better next time... Even if the smallholding thing is my dream more than his, I cannot do it on my own, so we do have to compromise a lot... (otherwise I would have loads more animals!)
Maybe only running one sow in-pig at a time would reduce the stress a bit, but selling all up now would just mean you will loose colossal amounts of money (arks, fences, energisers etc etc - all the gear that you have just invested in!).
I know I shouldn't say this, but I find painkillers always work best with a few glasses of wine...
