I understand your situation. Memory problems and inattention may be due to depression or anxiety if it is of recent onset. If longstanding it may be due to adhd as well. Information regarding your sleep, hunger, energy levels and concentration at whatever you do would be more helpful to decide on the severity of your condition. It is easily manageable with appropriate treatment. Some counselling sessions along with medical help might be useful for you. My clinic is at OMR chennai. I speak tamil as well. I would also be more than happy to help you with that if you are looking for online assistance. You can directly consult with me through Practo as needed. Online chat consultation is also available.
