Dont take this the wrong way but at work we use something called Rescue Remedy at work for the dogs, it can be used by people too, one of the staff at work swears by it. Its all herbal so it safe to use. Maybe seeing if you can see a doctor about it if its getting too much for you to cope on your own? Do you have someone to vent to when things get too much? If you ever need to talk you can PM me
Sorry your feeling that way
