You sleep for a long time, and a little long. Generally speaking, 7 hours of sleep is enough for people, but you should ensure the quality of sleep. How is your sleep quality? How long did you sleep deeply? Although some people sleep for a long time, they all dream or wake up in a light sleep state, and their competitive state will not be very good the next day. Ensure your insomnia duration and sleep quality. It's best to drink a glass of milk before going to bed, and don't put too much pressure on yourself, so it's easy to sleep badly and your body can't relax. If you have enough sleep and good sleep quality, I suggest you go to the hospital for a check-up to see if there is anything wrong with your body and ask a doctor to help you recover.
