How To Treat Tumor In Pituitary Gland?

I am a 30 year old female with health problems. I was diagnosed with a tumor on my pituitary gland after having high prolactin levels. Recently my blood work showed low iron, low hemoglobin, low magnesium, low potassium, low calcium and a high white blood cell count. I ve been very tired, weak, sore, and just very exhausted with no ambition for anything in my daily life. I am concerned for myself as is people around me notice the big difference in my overall health. I am searching for answers to be healthier. Please inform me of the possibilities of what this could mean! Thank you for your time and expertise on the matter.
