That's says a lot about the quality of the book.
While it's on my TBR, this is one of the books that I have never heard someone dislike. I think I want to wait until I have a physical copy to read it since it's so well liked. I have a few books that I need to get through first so I still have some time to make up my mind.
I know life is tiring but just in case you are also physically tired from lack of sleep. I recommend taking 5 mg of melatonin, if you have 8 hours of sleep available, for a few days.
There are times when I don't sleep well, tossing turning etc, and melatonin every so often helps me catch up on a good night's sleep. I'll wake up feeling a lot better.
It won't solve your life problems but it will help alleviate the unwanted feelings from not sleepy well.
I hope things work out for you.
