It sounds like you're tired, and maybe now is a time to rest, be comforted, and maybe find a funny movie to watch.
On a physical level, your brain has been working hard, and that means you have a build-up of different hormones in your body. Water can be very helpful to help balance that out. Drink extra fluids, and/or take a nice bath. (I've found baths to be really helpful for me when I'm feeling emotional.)
On an emotional level, it is possible that all the internal work you've been doing has now allowed you to feel things more deeply. This is a very positive step, but it can feel overwhelming if we don't expect it. Remind yourself that if you can feel the sadness stronger, that also means you can embrace the joys of life even more.
Most importantly, be kind to yourself. You are still the same beautiful, special person you were yesterday. Finding balance in life is not limited to a single day -- sometimes what we do one day/week then needs to be balanced out the next. I often think of the ocean waves...the tide moves in, and then gently back out again. It is a balanced cycle, yet it is always changing.
Many warm and supportive thoughts for you.
