Thanks, yes he mentioned that we may never get the answer as to what caused it but we need to focus on the minor mood shifts and see what I feel when that happens. Thing is I don't know what I feel / think when my mood changes actually it's usually a combination of thing that has happened during the day (small things) and then a silly thing like the tv being too loud and my toddler shouting at the same time I think my brain gets a overload and then he just says ENOUGH!! ( Does it even make sense? )
