AuSsieGirl,
Your friend could be showing signs of manic depression, it is always triggered by season change.(late Sept.,Oct., and spring around Easter weekend) What you have described CAN be a sign of manic depression but it is hard to make a diagnoses from just that alone. It is usually accompanied by other symptoms that you may not have noticed but it will have to be determined by a Doctor.
Other signs that you should watch for are unusuall behaviour such as: depression.....suicidal thoughts........aggression, anger and/or violence......rapid mood swings..........always talking religion(saw the Lord).........rapid cycling (always talking about things that arn't making any sense(won't shut up)).........Dual personality.......kind hearted (more than usuall).........urge to want to spend money on thigs she doesn't need or urge to spend other people's money.......poor sleeping habits.....poor eating habits......these are some of the signs to look for.
If she is showing more than one of these symptoms than she should be reffered to a Doctor.
Good Luck

I would say that if she is displaying more than one of these symptoms than it's POSSIBLE that she may be manic.
