Hi Lavasha and welcome.
I am so very sorry to hear about
the loss of your brother. The death of a loved one is of course an understandable trigger for anxiety...
...so know that a lot of what you are going through is situational, and your struggle will not always be this difficult.
However, it is still recommended that you do all that you can to manage the anxiety, so that it can diminish as your grieving continues.
You have gone to see your doctor...were you able to come up with a plan for relief? Medication and/or therapy are the usual options that people consider.
Self help is another recommendation I always make...and one that you can get started on right away. Here is the link to our Resources, filled with great material. Have a look and try some of the suggested reading and exercises.
