The best ochem book I've ever used (and I was a biochem major in undergrad) was Organic Chemistry by Leroy Wade - very concise and easy to understand (the book by John McMurry is also pretty helpful). I self-taught myself with the book since I didn't like the assigned TB and passed OchemI-III with A's.
For biochem - Lehninger was what I liked but the book can be a bit much for someone new to the material. I'd supplement with something like Biochem for dummies.
Finally use Khan Academy (and youtube in general) to look up/learn. Good luck but there's honestly so much material out there that learning ochem/biochem isn't as hard as it used to be.
