Addy....please call your doctor and tell him/her how you are feeling...tell the dr. honestly so you can get the help you need. I am amazed at how much better I am feeling since taking this "calming" pill...yes, sometimes I think of it as a magic pill.
There is no shame in needing help...do call your sister too.
I'm glad you trust us enough to share what you are feeling...you aren't alone.
