Not necessarily lonely. I think there are three situations one can be in when they are by themselves:
1) Alone (on their own, with no-one to call on or help them if needed). Alone is a physical state.
2) Lonely (on their own, with a need for human company & human interaction). Lonely is an emotional state.
3) Solitude (on their own but not feeling alone or lonely, and quite okay with that)
Of course, one can also feel quite lonely even when surrounded by lots of people, if there is no connection with them.
