But unfortunately, when he was alive he did not have a happy life. Van Gogh was from a poor family in Holland and lived most of his life at home. He lived a rather sad and (iii) _______ life. He drew things that he could sec cither around the quiet town of his parents’ home or outside his window. This was why he painted things like the sky, his room and even himself. Van Gogh once cut off his own car after drawing a picture of himself. He cut it off to show the person that said the ear in Van Gogh’s painting was not correct. It was very unfortunate of him to do such a thing. Van Gogh was also called a crazy man. He really did become crazy, and was sent to a mental hospital. Sadly, he killed himself when he was just 37.

Lolita_(✿˵◕ ɜ◕˵)Lonely = buồn tẻ đơn độc (vì ở một mình)
=> Nó sẽ mang nhiều nét cảm xúc khi miêu tả hơn
Khi xét vào ngữ cảnh câu văn: Ông ấy thích sống một cuộc đời đau buồn, cô đơn nghe nó rất là hợp lý
Ngoài ra bạn sẽ thường thấy lonely được sử dụng rất nhiều khi diễn tả sự cô đơn

Lone = lẻ loi (từ lone + noun để nói về một thứ biệt lập, lẻ loi)
