Whether you do your own taxes or not, you must usually collect data in various categories (medical, charitable contributions, business expenses, etc.) before that can happen.
To make it less stressful, pull together one category at a time, spread over several days. Before long, you'll have each category neatly organized and itemized, ready for your accountant or when you do your own taxes.
Put on some of your favorite music or watch a movie (if you are able to multitask in this way) to make it more bearable.
By getting each category completed ahead of time, preparing your taxes won't be such an overwhelming task!
