Pls give me some suggestions. Happy.

I understand your situation. You seem to be suffering from significant health anxiety symptoms related to cancer. Just because someone you loved had blood cancer doesn't absolutely mean you might develop it as well. You have developed few depressive symptoms too because of the anxiety, including difficulty in concentration, loss of interest and feeling low. Information regarding your sleep, hunger and energy levels too would be more helpful to decide the severity of your condition. However it is easily manageable with appropriate treatment. Some counselling sessions along with 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 also available.
