Daughter just diagnosed with Bipolar Disorder...help needed, please.

[BeHereNow]

I've been on a helluva ride with my 21 year old daughter this year guys.
FINALLY, we saw a doctor today who explained what's been going on.

From what I have researched about BPD tonight, it would appear that
she has just gone through her first episode.
Starting sometime last fall with a several month long depression,
a short period of plateau, and most recently the most frightening
manic behavior I have ever seen.

EXTREMELY high risk behaviors accompanied by rapid,
blurting speech patterns that indicate feelings of
invincibility and well, grandiosity.
She also becomes VERY aggitated and explosive if
interrupted or an attempt to reason with her is made.
(The doctor told me I was wasting my time trying to
reason with her when she is manic due to the euphoria she felt)
I thought we were going to get thrown out of a
store on Saturday, she was acting so wildly.
I whispered to her that she needed to calm down
and she whipped around and said in the
staccato speech pattern, "BUT I'M HAPPYYYYYY. Dammit!!!"

The deression scared me pretty bad, but I think
the mania actually scares me worse.
I fear for her physical safety.
From what I can tell, she has a tendency to really
piss some people off, especially if she drinks alcohol.

Thye doctor said it is typical for BPD people to self
medicate with substances,

We are going to be advised on a mood stablizer medication
tomorrow.

I am relieved to finally know what the hell has
been happening over last 9 months, but also scared.

I would appreciate any fellow DUers with experience
in BPD, either personally or with a loved one, to share
and advise.
(On edit: In particular your experience with
the various mood stablizers prescribed for controlling the highs and
lows.)
I'm so exhausted... from dealing with it for so long.
I could use some advice.

Thanks in advance.
