What are some issues Jimi Hendrix experience?

I am doing a verbal essay on Jimi Hendrix. The problem is that i've only read 80 out of 330 pages of the biograph : "Jimi Hendrix : The intimate story of a betrayed rockstar" I sort of need a summary of what happened in the book because i need to know what are a few problems he experiences throughout the story. I know that drugs and fame are some. but i need more. and it's due very soon and i don't have the time to read the rest of the book. Thank you
