וירא ה' כי שנואה לאה
Could it be that Yaakov Avinu hated Leah? R' Baruch Simon quoted from the Rebbe R' Simcha Bunim the following explanation which is very relevant today. Leah hated herself. She thought that she was not worthy to be married to Yaakov. The pasuk is describing her feelings not the way Yaakov felt about her. Hashem gave her children to help her improve her self esteem.
