Living with someone who has depression

Hi Guys, dads new girlfriend moved in about 2years again and has been diagnosed with manic depression. I have read a few threads about sufferers but i just wanted to let u know how it is for people around you.
She is a lovely lady and i really like her alot but myself and my sister just never know what to do or say around her you never know what shes like one minute to the next, we could do something together have a whale of a time and the next minute shes slamming doors screaming at my dad and generally making our home very unlivable.
Its very difficult not to get caught up in it and start feeling depressed myself as dad trys his hardest bless him.I jus feel i need advice on how to deal with living with someone who is suffering i so want to help her and make her happy again. make us all happy really.

How old r u girls....seems like a selfish move on your dads part.....u shouldnt have to deal with that.

Im 21 and my sis is 19, dad didnt realise she was this bad, but they wernt together long before she moved in he admits now he's been selfish. sometimes i feel asif im hittin my head on a brick wall.

No, your dad has a right to seek love. You would too if you were him. Now its not selfish, why because she has a problem? People always look at mental disoders in the wrong way, if you think its bad for you think of how it must be for her to make her act that way.

You are 19 and 21 your old enough to move out of the house of you want to. Its not like you need to be taken care of like a toddler anymore, it sounds to me your the one being selfish.

You have to be compassionate and understanding, causing more conflict will only make things worse.

Encourage her, and or your dad to seek counciling, possibly medications. Overreacting, and causing conflict like I said, will only make life hell for everyone involved. Right now, it seems like she is apart of your family so why don't you start treating her like one.

I agree with lonley fading that you can seek help as long as everyone is on board. As long as you and your dad have a good relationship then things should work out.

Well that didnt help me very much at all. I came on here for support as i have no one else to talk to about it. Obviously the wrong place to ask for help..

ummm what response were you wishing for? I think we all gave you the best insight possible.

Yes you're EVIL and just out to cause TROUBLE! Dad's g/f is obviously a SAINT so why don't you start treating her like one??

Disclaimers on above info..
1 Drunk
2 Clueless
3 Unresolved anger issues

P.S. Causing conflict here will just make things worse, try to be much more compassionate and understanding that's my advice.

I didn't mean to be mean but you got to understand whats wrong with her is a real clinical illness caused by something being wrong inside the body. Just like diabeties, just like cancer

You need to help her if you want your dad to be happy. Look up things, but don't be pushy, and don't ever be mean to her because it will be easier for her to set off.

Trust me, her life is hell, mental disorders are hell. She needs help and your an importaint person to support her.
