mood swings are certainly typical of bipolar behaviour. I have had friends with different levels of this problem, so have seen it from the outside, as it were. I have always longed to help, but I realise now that amateur help is worse than useless. Too often, the sufferer latches on to any non-professional offer of help, for fear of being sent to some "facility" by the professionals. If a sufferer latches on to non-professional help, they then fail to receive the help which will actually be of some use to them.
