In this website, it talks about how Mark Rothko had a very hard childhood and this is what caused his suicide. He experience early losses from his family. They don’t say who he lost but it was someone that was very meaningful to him because from that day and one, he was depressed and not that mentally well. I am not saying that he was crazy but that he was not well because he was alone and it was hard growing up without that person. When a kid is growing up and there isn’t that much love in his family, then he grows up to not be that loving or happy person. This is not for all people but it was in this case. He didn’t get marry or he didn’t have any relationships when he killed himself because he would also have attitude issues and he would just start to scream. He would scream because he didn’t want to hear what people were saying and this cause the women not to date him or get near him. He was always depressed and no wonders why his art was usually dark and not that complex because maybe this is how he felt with his life. This is the background of why he suicide himself.
