Understanding and waiting for comfort

I feel exhausted. Being productive but another headache comes, deep and aching. It remains this away. No it’s not the pain, that bothers me. But the inability to remain fully present. Plagued by either bad memories or distraught by the evil, I witness. How do I keep living normally, when my mind is not well. Too tired to walk away let alone move away, because some days I’m still too tired or disoriented. Don’t know what to do next.
