I have been suffering from temporal lobe epilepsy since 2004. Later, I suffered from hashimoto's thyroiditis in 2015. In 2018, I suffered minor cardiac event and a stent was put in left main artery.  Recently, I was diagnosed with diastolic dysfunction grade 2.  Thereafter, I suffered from anxiety and depression. Currently, I take : Deplatt CV bd, Ivabradine 5mg bd, Nebicard SM of, Zeptol CR 400 mg bd, Zosert 75 mg ( 25 morning + 50 night), Thyronorm 37.5 mg and Pantop D SR. Since my health is fragile,  I have few questions: (1) Because of cardiac event, I want to go for brain surgery to be free from epilepsy. Whether it is possible or not ? What other options do I have ? (2) Am I on adequate cardiac medicines to manage my condition ?
