Hi
That happen to me all the time - you're def not the only one who struggles to recognise themselves, I change so much from day to day, and throughout the day and what I say and how I say is ruled by my 'mood' at that time. I often say things I can't recognise the next day, It's like, I know I said it, I know I did it but I can't relate to it because my mood has changed. I see things differently depending on my mood, and I interpret things differently too.
Anyway, you're not the only one, OK
