Books to be read

Hello Dhananjay Sir

Its been two months of my brahmacharya practice, I live alone in a room, and nowadays I feel very lonely, I just keep sitting or sleeping or searching on internet.
Earlier when I used to feel lonely(it was rare though because I was in a P.G), I saw movies and porn, but now I feel its not worth watching.

Q.What constructive activity I should do when I feel lonely, I do not like studying these financial subjects, nor I m able to meditate, but I am interested in reading the Vedas and The Bhagvad Gita, I would have gone for it but people say its difficult to understand without teacher.
Which book should I go for as a beginner?

Thanks
