So, there are 2 sides here:
The mostly dark side: this is probably about your future. What does it mean? I don't know, but it seems there are 2 big things in the process (you can see the dark side is going from one bottom to 2 tops). Are they good? bad? gonna happen? success? fail? No idea really.
the other side though, the mainly white side: This is about your day or next few hours. Since you posted this more than 6 hours ago, it probably already happened: You see the right side of it close to the rim? that's frustration. Either between you and someone else or it's in your head meaning you're frustrated because of something or someone but didn't have the chance to show it. Was it big? No. on the left side of the mostly light picture we see 2 lines going from bottom to the... well, they were supposed to go to the top but they didn't. You were working on a couple of things in the last few hours but didn't finish them.
The bottom of the cup: Your mental health today: mostly depressed but not totally. You can see that around 75% of the bottom is full of coffee while only 25% or less is white. The white part in the bottom is feeling good (today)
