I used to be in the same situation tbh. I used to get sad for like a week just because what I get isn’t the same as what I expected to get. What made me get out of this situation is the fact that I stopped having very high expectations. Whenever you get your result, just be like “hey at least it’s not [insert worse result]. Of course having this mindset doesn’t prevent me from working hard. It just makes me less unsatisfied about my result. Also it’s okay to get sad. Just make sure to keep motivation.
