I understand your concern. However more clarity is needed regarding your actual problem. Don't worry it is not your fault, it is the hormonal and chemical fluctuations in your brain as a result of stress which is taking a toll on your mental health. Our brain has an inbuilt mechanism to recycle itself and store only useful memories so that more room is available for processing of the newly available information. Any issue is easily manageable with appropriate suggestions, so that dysfunction due to the same can be reduced and your quality of life will improve. Some counselling sessions and if needed medical help might be useful for you. I would also be more than happy to help you with that if you are looking for online assistance. Discussions will be held confidential. You can directly consult with me through Practo as needed. Online chat consultation is available.
