...seconds. What do I do? I've asked her a few things and she has told me that she feels all upbeat and happy then feels like depressed. It usually occurs when she is alone. She has only told me about this and her bestfriend. She says she feels as if nothing matters and there's nothing to live for when she is in the sad state. They happen randomly and this has been going on for half a year. I fear it could be serious or become serious, she means alot to me and I'm really concerned. Please help!!
