is it my fault for falling back asleep again or my brains fault? I woke up at 8am and fell back asleep till 9am, then I woke up again and fell back asleep and couldn't seem to get up.

It may not be clear whose fault it is for falling back asleep, as both your brain and your own actions play a role in determining whether you wake up or fall back asleep. It is important to listen to your body and understand why you may be feeling tired and lacking the motivation to get up. It could be due to various factors such as not getting enough quality sleep, stress, or a disrupted sleep schedule. It may be helpful to establish a consistent sleep routine and practice good sleep hygiene habits to improve your quality of sleep and prevent falling back asleep unintentionally.
