So make tomorrow the first day of the rest of your life and keep a positive attitude. I know it's not always he easiest thing to do, but when you find yourself overwhelmed with anything.......too much work to do, too many thoughts running through your head....whatever it is. Stop. Stop whatever your doing, sit down, start paying attention to your breathing and try to take each thing that has you feeling like you're going to lose your mind and try to deal with them one by one. Have a little patience and faith in yourself.
After this you've got me confessing to an entire bag of donut holes, so some good is coming out of it lol.
