My 15 year old daughter has been complaining to me that she feels like someone or something is following her around the house. Apparently, she can't see it or hear it, but it is like an oppression of some sort that makes her feel paranoid. Also, she says it is worse in darkness, but even at school, she feels like it/he is there. She can't really discern any gender or detail about this 'entity', but she feels like it is dreadful, always watching her, and that it might do something. Mostly, she feels like it's behind her, and when she turns to see something, it's not there and she feels stupid for looking.

Personally, I don't believe in ghosts. I think I would have sensed something that's amiss, but then again, maybe not.

After talking to her about options, she says she is worried that this could all be in her head after all. I have no idea how to help her. If we go to a psychologist, I feel like we'll get laughed at or told that this is just a paranoid manifestation of some sort. To be honest, I don't know what to expect. Do they take this sort of thing seriously?

This is really bothering her, and it has been for over a year now. I used to think she was just acting out for attention, (kind of still do...) but I feel like I should do something....just not sure what. Suggestions?
