I'm sorry about the lose of your brother. I know that was hard for you. I'm glad you can see the happy times you had with him and remember him that way. I don't know how bad your friends are right now but like with your brother and just be there for them. If the worst happens you will know you did your best to their friend. I hope they are not in serious condition and recover soon. Take care of yourself in the meantime. Like eat regularly and get some sleep.
