Oh apples sorry you are having a hard time at work. I am retired now but when I was working I used life style changes to help me cope better. When the stress got too much I retreated to the bathroom and practiced mindfulness or exercised till things were manageable.
Here are some of the things that help me. I have to watch what I eat because foods I eat can stabilize my moods or exaggerate them. A high protein low carb diet with snacks or meals every 3-4 hours will over time reduce my swings. I also avoid alcohol and recreational drugs because those can really increase depression.
Other lifestyle changes that help me are doing yoga, exercises, mindfulness, calm music, and being active on Psych Central.
Besides helping support each other many people here at PC also have a therapist to talk things out and a psychiatrist or psych doc to diagnose and prescribe meds to help balance things our.
The depression chat meets every Thursday night 9pm. Anxiety chat on Friday night 8pm EST.
Some people find the forums give them the compassion and empathy they seek.
