Does stress effect lymphocyte count

I have, since I can remember, been anxious and under stress.  My lymphocyte count has usually been a little below the low range, ie., 20-40, and around a count of 17.  My last blood test result was a lymphocyte count of 11.  I have been under greater stress recently.   Could this greater stress cause my lymphocytes to decrease to this low number.  Thanks

According to Laboratory and Diagnostic Tests with Nursing Implications by Joyce Lefever Kee excess adrenocortical hormone secretion can decrease the number of lymphocytes.  Cortisol is an example of such a hormone.  It is released under times of stress.  There are blood tests available to determine if  you have excess cortisol in your blood.
However, there are many disease processes which can lower the lymphocyte count as well.  Have you had a thorough exam?
