I'm not surprised you are irritable and emotional - your body and mind have been through a HUGE ordeal.
As Jane has said, a good cry can sometimes help - I feel like I could have filled an ocean since my diagnosis last year and even now have the odd wobbly day. Sometimes a good howl really can give you a physical as well as an emotional release.
Hopefully now you are home, you will be able to rest a bit better and won't have the annoyances of hospital wards. Be kind to yourself and rest when your body tells you to, don't try to fight it.
Hi Horseslave (LOVE the name by the way, I am also slave to a horse!)
Hoping it all went as well as possible yesterday and you're beginning your recovery.
Love and hugs
All the best for today Horseslave, my surgery was a week ago and am waiting for results now !
Are you staying in overnight then if you are later today
