My girlfriend has anxiety problems. Taking it slow?

My girlfriend is having ssues with her anxiety. She was living with me for months when her anxtiety began to tart a few weeks ago. It really scared her at first and we had to call the paramedics. She was on a few different medications and is now trying Prozac. She says it is starting to work but she cannot see me because everytime she gets around me she becomes scared and starts having an anxity attack. She also thinks my house is a bad place. I blessed my house and am supporting her, over text, in every way that I can. Telling her everything is going to be okay, staying up late with her because she can't sleep well and I am afraid she could become an insomniac. I truely hope the prozac helps her sort out all the things she can, but also I know me and her need to take our relationship slowly. I don't know how to slow things down though. I love her to death and would never let anything happen to her. Anxiety, though, I cannot stop, or fix. So please, any advice on how to handle the situation, or make her feel better, or how to keep our relationship from falling apart would be very helpful. Thank you.
