re-used content

I have 240k subs and I'm kind of upset with YouTube that they demonetize me TODAY for reuse content when it is 100% original content and I don't understand! it's a Channel about MY dog and my family - how can I be using someone else's content when it's literally my life! has anyone experienced this? - and moderators please stop directing me to a 5 year old thread noone looks at.
