Anyone else’s parents behavior resembles children and you feel like you never acted like a “kid.”

Maybe I’m not explaining it the best but all my life my parents have had a very toxic relationship with eachother. They love me very much and have always showed it. However there own life experiences and other day to day things make them irritable depressed etc and they make it obviously known. Me on the other hand have never really displayed any sort of emotion. I’m always happy or content. Granted on the inside I might be extremely stressed but I’m rarely outwardly displaying this. So long as they ok I’m ok. My family remarks how I’m really ever in a bad mood from my teenage to adult years
