First... slow down. If you know baseball at all, there's a saying that goes, "You can't hit a 6-run home run." (The most you can get is with the bases loaded, and that's a 4-run home run, or "grand slam.") So don't try to do more than is possible.
Don't try to solve everything in a day. It can't be done unless there is a miracle provided you by grace.
Take it ONE DAY at a time. Can you get through today? Yes. What can you do TODAY that will address ONE THING that you need to deal with? You don't have to SOLVE that one thing today, but you can at least take the first step towards solving it.
Have faith. Faith in yourself to handle those burdens you have to carry. Faith in your friends that they will help you carry them. Faith in God to know you are not alone.
