You gotta just stand up. Even if you walk around with your eyes barely open, it's better than laying back down. Waking up in the middle of a shower is a heck of a lot better than waking up late for work
I don't know if it'll help you, but I envision myself as having two mes: Sleep Me and Awake Me. Sleep Me is an asshole who'll ruin my life just to stay asleep for as long as possible. He fights tooth and nail to keep Awake Me from taking control of my body. ”I'm gonna go back to sleep" is Sleep You talking. They're trying their hardest to convince Awake You that you can't possibly stand up until Sleep You has had their fill of sleep, but it's not like "just be happy" or "just pay attention–" you can control your legs!
That's Sleep You talking! FUCK Sleep You! They don't give a shit about you, or your success in life, or your mental health. They exist solely to make sure you sleep as much as possible and they're given way too much power to achieve that goal
My one cat usually sleeps on top of me so I can't just stand up. And when he isn't sleeping on me and the alarm goes off, he'll come in running for snuggles and make me fall asleep again.
Cats are truly our greatest enemy in life. My Athena doesn't much care for Awake Me, but as soon as I fall asleep she wants to be as close as possible. If I didn't grab my phone, I'd be back to sleep cuddling her as I type this
I set up some smart bulbs and music after I turn off my alarm. Having light and sound stimulation has prevented me from falling back asleep even when I'm so tired I cannot keep my eyes open.
Sleep as Android has this along with a ton of other wake up helpers like QRcode/NFC tag scanning to stop the alarm, math problems, etc.
I found the math worked well at first but I apparently got too good at solving them in my sleep.
I put an NFC tag in the bathroom which requires me to get out of bed and go into the bathroom to stop the alarm. That's usually enough to get me to stay up
They also have various CAPTCHA tests, one that requires you to hold your phone and spin around, one that requires you to put the phone up to a light source, and other such things. I'm sure you can find an effective solution that works for you
That's why I placed my alarm on the other side of the room. This way I have to get my lazy ass out of the bed to turn it off. And then I'm awake anyway.
The clock app on Android is seriously great software. I have myself playing guitar to wake me up and have trained myself to snooze if I am still in bed.
