How to feel emotions?

I often overeat at work cause i feel stressed out, anxious, overwhelmed, frustated and angry all at once and i have thoughts i cant handle all these emotions together or I resist feeling them and seek comfort or buffer with food. Sometimes it’s because i’ve done part of the work but then i have to pass it overtime to do their part before it can be completed and processed but i have a manual for the other person, i want them to care as much as i do and work quickly and efficiently so when i think they are not i feel all these emotions as others are asking me for the work but i can’t do anything so then i go to food. This happens often i noticed so i want to stop this pattern and work on it. Any advice Brooke? Thanks
