Drinking Tea and Breast Pumping

Naylea
So I have really bad stress and I believe anxiety to the point my hair is falling out. Excessively.... I even have some what of a bald spot. It's so sad. So I started only pumping in the morning and night and sometimes once more during the morning when my LO wakes up. Well I want to drink a stress relieving tea during the day but I was wondering if it's going to affect my milk? I usually drink coffee after pumping in the morning and it doesn't seem to affect my LO. I was just wondering if anyone has a similar experience.
Thanks!
