Hello and welcome to Healthcare Magic. Thanks for your query.
I'm sorry to hear about your brother's death and can understand how difficult and stressful this situation must be for you. Your symptoms seem to be indicative of depression
(which has been precipitated by the sudden, extreme stress). I would advise you to consult a psychiatrist
for a detailed psychological assessment and further treatment. There are effective treatment options in the form of medication and counselling
which will help you handle your emotional problems. So, please don't hesitate to seek professional help.
Wish you all the best.
- Dr. Jonas Sundarakumar
