How do I help my friend?

Perhaps your friend is feeling a little like she's drowning. She's in her mid-30's you say, she has her own life, her independence and with everyone clamouring around her trying to show her they care, it's like being a teenager all over again getting berated for wearing something forbidden or missing curfew.
I'd back down for a while, but still show support for her. If you're worried she is having a mental break down, go see your doctor and ask advice on what the appropriate way to go would be. Ask around for leaflets on mental health, and slip them to her when she's in a good mood. Trawl the internet to find out what illness she may have. Different mental illnesses have different factors, mood swings, appearance, how she talks and walks and what she eats, all can be clues as to what is happening inside her mind.
She may be hanging up on you because all you want to talk about is the problem she's facing, which if it is mental can make her more distant and weary of you and your intentions. try ringing her again but instead of focusing on what happened and why and talking about the problem, ask her round for tea and a chat, or to watch a movie together one night. how about a night on the town so you can both relax. If you treat her normally (even when she goes off the rails with mood swings etc) the trust she had in you will be re-kindled and in her own time she may open up a little bit more.
You could try going to the police station yourself, and asking their advice on what you can do for her, seeing as officers there should be trained to deal with the repercussions of sexual violations, domestic abuse etc.
To be honest, it sounds as though you yourself need a break. What would happen to you friend if you're trying so hard to get her better that you yourself turn ill? That would be helping no one.
First and foremost you must remember she is a grown woman, she has her life away from you too, and if she needs to handle this on her own so be it, but always be there to support her with whatever decision she makes.
In my experience, i've learnt that a good friend will on one occasion barell in guns blazing to defend their friend and then when the time is appropriate, step back and support but allow the friend to take the helm.
Whatever is going on, i hope your friend gets better soon and realised what a good friend you are. Hope everything turns out well X

Maybe that is why she called the cops. She saw what she was becoming and it was because of him. Call her again and tell her it is not your own business but you care.

Well don't take this the wrong way but I fear it may be her age I am in my mid 30s and so is my friend and she and I are both doing things out of character. I have feelings for someone who I can not have for any number of reasons but can not get him out of my head and my friend is making out of character decisions that 5 years ago she would not have made. OK so as she has called the police what ever the problem is will obviously be serious. As her friend I am sure you have told her in the past that your here for her. First things first if a phone call will not work write her a letter put it in a nice card (I make all mine so its very personal) then in the letter tell her how you feel remind her if she needs you she knows where you are repeat all your contact details including email and anything else. Then wait probably about 4 weeks would work well and if in that time you have not heard anything ring her up and see how she reacts I did something similar with my friend and although we are not communicating regularly she has been intouch and so my mind has been put at rest. Hope this helps. Good Luck
