Alarm anxiety...

When I know I have an alarm set for 6/7 am in the morning I get so stressed at night and stress if I don't sleep I will only get x amount of sleep and I constantly check the time on my phone. Its awful I know. I need a solution lol...I really want to put my phone in a different room but thats how I set my alarm. I am considering getting a hatch but I have heard mixed reviews and I don't want to spend $200+ and pay each month for their app. Does anybody have any advice or would recommend a different alarm clock?
