I sleep at day just because I need at least 3 hours before school for overthinking and psyching myself up. If i don't do so I won't be able to function properly. I would probably stay in bed and not attend classes because my stress levels in the morning are too much for me to bare. 
I truly tried to sleep during the night, like I'm spouse to, but I'm unable to get up until my anxiety makes me think about the conversation with my teachers about my absence that day. 
Do you have any tips that could help me? pls i wanna talk to people. everyone is asleep and im going crazy
