wish there was something to say to make it better... like Beth says, reach out to your doctors and if possible to the people that you trust. We are here for you to talk to, to vent and let out all the frustrations. We do understand something of what you are going through, because although every one is different we have all had our own struggles and know what it is like to be out of control, so don't be afraid we won't judge you or be shocked.
When the pressure gets to much at work, I escape to the toilet or take a walk around the building, just to try and get under control. Try practicing mini meditations where you focus on only your breathing for a minute or even 30 secs, the more you practice the more you can do it when you need to.
Love and best wishes, keep on going, it will get better.
