suggest books

Can I get some book recommendations - lately feeling very low and unhappy - still not able to figure out the reason. Basically struggling to have a STRUCTURE IN LIFE thus that's making me paranoid, I won't read fiction and pls suggest ones which are good reads but not sophisticated English I already wasted 600/- on books which I couldn't read primary example autobiography of yogi , would love good self help, psychology, mythology - ones which i can read 20-30 pages per day.

Thanks in advance
