What Should I Do If I Have Inability To Stay Focused, Head And Ear Pressure, Irritability, And Lack Of Energy?

I have difficulty staying focused for a period of time. My mind hits the wall all day till I am ashamed. I have pressure in my head and ears. I'm very irritable and I don't have any energy. I have been to the doctor to have my thyroid and blood checked which both came back normal. I was diagnosed with ADHD a while back and the doctor gave me Strattera which didn't work. I'm currently taking Welbutrin which isn't working either. My main concern is my inability to stay focused, head and ear pressure, irritability, and my lack of energy. It's like I'm walking in a bubble with no energy. Thanks for taking the time to read this
