please rephrase that question to: What steps should i take in my much needed bulk.
Yes bro, if you weight that little you need some mass on you. Start eating more, I know youre young but that really isnt an excuse. Many of my friends as well as I weighed much more than that in an athletic state at that age. Eat-take protein-lift-sleep repeat.
*Edit: youll probably be better off re-posting in the Beginners forum where people can help your diet and current lifting plan.
