testosterone threapy and depression

been on testosterone injec. for 18months also on Prozac 10yrs for depression.results were great libido returned
felt very good.last blood test showed red blood a little high Urologist took me off shots for 6wks then  will get another
blood test. my question is since i have been off the shots my depression has gotten worse,feeling down no energy,
no libido,the prozac doesn't seem to cover this hormone.these shots made me feel much better then the prozac
alone.any suggestions would help. thank you
