I'm so sorry you are going through a stressful situation and cannot fix it or see a resolution in the foreseeable future. (((Hugs)))). That sounds like a very unpleasant situation to be in and my heart goes out to you.

My mother is a chronic worrier and so am I. Our medical Primary care physician says some people are just like this and prescribes Ativan which I do not find helpful and he encourages it to be used sparingly which does nothing for my tendency towards chronic near constant worrying. My PDOC says it's a mental health disorder and needs to be addressed through daily use of AP's and the like. He prescribed Klonopin to be used in extreme cases.

The only things that help me when very anxious is writing or talking about my feelings with someone I trust....warm baths when available can be soothing. Breathing exercises work sometime but like RX said, if I'm too far gone it's time for a Klonopin. I plan to REALLY learn how to meditate. The author Sam Harris who is a neuroscientist wrote a book about it and I plan to start reading it since I've read some of his other books and respect his expertise. It's not as easy as telling someone to just not worry but I did find that when I deeply understood at a cellular level that worry helps nothing and tends to make things worse overall it helped me to keep things in perspective *sometimes*
