Wanting to get skinny and more disciplined

Listen here idk how people workout I try to keep a routine it may work for a week but not proper I skip sundays n then wait for Monday I wanna get up early to go but I can barely get up I need to study more to so i can't get to much sleep I really wanna lose weight even studying is hard for me I've tried motivational videos I've tried jus starting it's like my brain jus processes it as a trivk even wen I keep a reward system it doesn't work it's like I can jus eat it now wtf is stopping me fyi I wouldn't really say eating is a problem as long as I'm not awake but yea u get the idea maybe I'm a bit problematic with the schedule
