I’ve fallen way behind at work, partly due to being burnt out, but mostly due to an overwhelming amount of extra work during the holidays. That extra work means getting back to customers later than I expected, and it’s snowballing. Now I’m afraid to open their emails and listen to their voicemails, because they likely contain frustration that is directed toward me specifically (for not getting back to them sooner, or their multiple attempts to reach me).

Any advice?
