In the video it is her dad in the astronaut suit so I think she is personally talking about her relationship with her father not any romantic relationship but I agree with fadedmemories I think it could be about anything e.g. religious beliefs, boyfriend/girlfriend, friends, parents, etc that acted as your guide or comfort but now that you don't have it you don't know what to do and don't know where to turn and you are lost.
