I'm writing this in the hope that it will help some people understand, and avert the possibly catastrophic out-come of an enthusiastic, positive outlook. A couple of days ago I nearly passed out on the stairs, I was carrying the cat down as he had had a fit. I felt a bit wobbly at the top of the stairs so did my usual on my bum routine. I had been feeling quite rough so put it down to foolishness, I should of known not to try the stairs. The Orthostatic Intolerance(OI) or Postural Orthostatic Tachycardia Syndrome (POTS) was stronger and lasted longer than it ever had before. Anyway a couple of days of being pretty much grounded, and a lot of bed rest and sleep, I woke up feeling fantastic. I honestly felt I could have run a marathon, I was full of beans. So when my granddaughter woke up before tea, I went up stairs to get her, my partner offered but I was feeling great and insisted I get her because I love seeing her when she's just woken up. Everything was fine, got up stairs easily, picked her up, put her on my left hip so I could hold the banister on the way down. I got to the top of the stairs and thought it would be wiser to go down on my bum. Thank God I did. We went down each step one, two, three, little one counting along with me. Less than half way down I started to feel feint, I called my partner. My daughter asked "are you OK Mum?" I answered with calm breezy, "Yeah fine", just as my partner came around the corner and took Molly, I stayed sat on the stairs holding onto the banister. The thing is I was convinced that I was well enough and strong enough to look after her. I also felt I could predict when I was likely to get OI indoors. I would have encouraged my daughter to go and visit with a friend, and my partner to go visit with our eldest daughter who is due on the 20thMarch, while I keep Molly at home with me. Thank God my daughter was unwell and that my partner felt she should come back earlier than planned. I don't know how long I could have sustained holding on to Molly and staying conscious. This has been the scariest moment in my history with this disease. I was distraught afterwards about the 'what ifs'. I'm totally shocked to realise I put my granddaughter in danger. I feel so stupid. It never once entered my head that it could be that strong and without any warning, especailly indoors. I truly feel we had a lucky break. Hopefully my lesson will serve as a timely warning or lucky break for many others. If you are a parent with toddlers please show this to the rest of your family and to anyone that may be able to grant you support. If you are a grandparent please show this to your children, and be aware that our optimism and enthusiasm can be dangerous to those we love. Oh and we need more bungalows.
