How to get away with stress during pregnancy?

Mommies, I'm currently 32 weeks pregnant and I have been going through a lot of stress with my work. Sobrang demanding pa din ng work ko and the management doesn't even consider the fact that I'm pregnant. Kahit ilang beses kong sinusubukan alisin sa isip ko lahat ng negativities from work, sumasagi pa din siya sa isip ko. I don't want it to affect my baby lalo na malapit na akong manganak. How do I control my emotions? Ayaw kong malunod sa stress at baka mag lead pa to post partum depression. Thank you sa mga sasagot.
