I tested positive for alarm clock fever

So I have this thing. I cannot just "sleep until I wake up". I used to do this, but I no longer can. I get nervous that I won't get up early enough to get everything done that I need to accomplish in a day. Long story short I set an alarm every night that will "wake me up" the next morning.
Problems with this:
I never get up when the alarm goes off and....
I hit snooze so much that my alarm stops going off and therefore I get up even later
I wake up to the alarm and then think, oh if i sleep for 30 more minutes I can just drive to class (this is problematic due to the amount of money I spend on meters and parking tickets)
I sometimes am still so tired that I grab my phone and somehow lie on top of it and therefore do not hear it going off in my slumber.
This final issue happened last semester. I was supposed to be doing a tour for a huge group of highschool students with m.cass at 10:30. I WOKE UP at 10:30. UM. So I was frantically freaking out and shitting my pants. m.cass had texted me asking where I was but I didn't get the message because I had somehow decided in my slumber that it was a great idea to place my phone at the foot of my bed/underneath my calf/basically under my mattress.
Lately I've just been hitting snooze for hours and not getting up until I absolutely have to.
Typically I set an alarm for around ten, hoping that I will get up and not sleep for seven days instead. However, I usually get to bed around three which creates a super over-tired simulation and then when my alarm goes off at 9:30/10 I can't seem to justify getting up when I was just so peacefully enjoying a slumber. I understand that 3:00AM-10:AM is seven hours. BUT by the time I go to bed at that measly 3:00AM I am so exhausted I don't even have the energy to read my book before bed (something I've been doing since the egyptians carved the sphinx). So after a day like that usually one needs approximately seven HUNDRED hours of sleep to recover. I, however, get little to none. On the days I am required to awaken at 8 I would rather die than drag myself out of bed.
Also, I've heard that lack of sleep effects short term memory. Well these days I have no recollection of something I did two minutes before I start to wonder about it. I usually have a very good memory but lately I've been appointed to the position straggler. So I just straggle behind.
Also, if I am going to be late to class I just don't go. This poses another problem because if I rush to class I will be sweaty as fuck and not want to go in because when someone walks into class late who looks at them? EVERYONE. So yes I would love to straggle on in dripping in sweat after trying to rush and having this happen

I wouldn't even go in. I would give up and go home.
