英语问题，句子改错

帮我看看这句话有毛病吗？从语法单词等等上来分析，
yesterday I went to bed at about ten, but I didn't go to sleep until 2:00am the next day, I was playing my phone on the bed, I went to sleep at about 2:00 but I didn't know when I fell asleep

Answer 1

Yesterday中Y大写，有个过去进行时的句子，改为一般过去时。最后一句改为but I didn‘t know when I was asleep.

Answer 2

Yesterday在句前的话首字母大写加，
at ten o’clock
i didn’t asleep

Answer 3
