Which Entity To Choose? Options

Greetings all.

I have been having a huge load of problems at home recently and was wondering if anyone could point me in the right direction concerning which /demon/angel/goetic/olympic/whatever spirit might be able to help in some way (obviously this would only be a temporary solution as I am moving out in the next 1 - 2 months). There is a brief description below:

At the present I am being forced (due to financial and other reasons) to live at home with my mother and her girlfriend. The problem is her girlfriend gives me vile verbal abuse, tries to intimidate me and when I was younger even to strangle me. She is an alcoholic and refuses to listen to reason about anything, especially her current state of mind. All of this is topped off by the fact that I have depression and anxiety problems which obviously she is making worse. She is really messing with my head (IMG:style_emoticons/default/insane.gif)

Please understand that I am not looking for sympathy! I am doing something to get out of this situation, I just require some magickal help to ease the tension while I get my stuff together.

All ideas and opinions welcome.

I appreciate and look forward to any replies I may receive.

I'm not a huge fan of cherrypicking entities based on their mythological reputation.

I much prefer to cultivate a deep relationship with a few entities (or a deity) and then if I need something, I'd seek their help, as a longtime friend. instead of picking an entity out of the phonebook and soliciting it's assistance.
I just think it yields better results.

obviously though, there are limits to this. For example, I'm pals with a nightmare entity, and he'd probably be a poor choice to ask to help out a friend who's having trouble sleeping hehe.
then again, on further reflection, maybe he'd be perfect for that... but it would be a sort of role reversal for him.

anyway, I'm sorry to hear that your living situation sucks like that. and I am sorely disappointed in your mother for allowing such hostility from her partner. if I had a child, and my lover were cruel to them, there'd be hell to pay.

I admire your strength by the way (IMG:style_emoticons/default/smile.gif)
