Can’t stay awake

Patient: I am a 37 year old mom of 5. I have been diagnosed with Generalized Anxiety Disorder and PTSD (from a car accident). I currently take Trazodone at night. My problem is extreme tiredness. I sleep at least 8-9 hours at night. I take B12 all day long under the tongue. I only drink one cup of coffee a day in the morning. I don’t drink pop. I try to get some exercise in when I can but its tough with the kids. I am so tired all day that I have trouble staying awake. I have had my thyroid checked and its normal. I did have a hysterectomy about a year ago and even though I kept my ovaries I take a low dose estrogen to help with hot flashes. Any ideas? Thanks!
