Something that still eats at me is her connections with Wicca ...even though it's a somewhat benign organization /group, couldn't individual members cause a problem?
Of course. Every religion has it's 'bad eggs', and this person telling your daughter she'd cursed her can be very intimidating and frightening, particularly if someone is already vulnerable mentally.
Reason asking: Now it looks like a younger sibling is showing signs of manic-depressive episodes. My sister-in-law is already getting him analysed and vitamin therapy is already started ...app't with a psycotherapist is on the horizon.
I can't help but wonder if there could have been something more to this 'curse' thing than meets the eye.
Firstly there's no proof of vitamins doing anything, medication is the best treatment for bipolar.
And the reason another sibling may have mood problems is that bipolar is often genetic, and other family members genetically prone to it. No spiritual 'curse' from outside involved :D
One of the first things shrinks asked my family when I first had a manic episode was 'is there a family history/ have other family members have problems such as this?'
People are at greater risk of mental health problems of all kinds if there's a family history. Having said this it may be the first time any mental health problem has turned up in your neices' family. But normally there's a history, at least of depression, in their mother's or father's families.
Here is one of the 1,160,000 :) articles online when one googles for bipolar + genetic:-
Remember this is just a risk, it would also depend on the life stresses a person has had and other circumstances. It's not a genetic 'curse', more like a risk, like other families have a higher risk of heart disease.
Hope this helps,
P.S. If you really don't feel happy about a 'curse' it would be easy to find a local wiccan who would do a ritual, probably for free, to break any chance of a curse and put your mind at rest.
