I am so sorry for your loss. I can't say anything better than what other people have responded to comfort you. I have the same feeling of stuck in the dead end job and I have been miserable for the past year because of my current job. I can't imagine how hard it has been for you with the job and your brother...I haven't heard back from any of my applications either. However, I believe that eventually we will find a way out. Hang in there!
