Cherry, yes, you are lean, accept it. You have very little fat laying under the skin, that is the definition of lean.
Frankly, if I were you and you really don't wish to eat more and/or gain weight/muscle I'd suggest you back off somewhat on your workouts. Anything more than three times a week of hard resistance training just becomes self defeating, especially if you include a few heavy compound moves. You'll just burn yourself out if you're going all out with training and not feeding it. I've seen it happen before. You can lose your gains. Remember what I said, you have to feed muscle.
BTW, I congratulate you on being able to be honest with yourself. A lot of people just don't have the insight to be realistic about what their goals truly are.
And you really have done a beautiful job, congratulations again
