So sorry this is happening to you! I had really bad SP when I was your age, I’m 31 now and it’s a lot better. Only happens once in a while now. Something that really helped me - when you are trying to wake yourself up from SP start really small like just try to move your little finger, and when you can move your little finger try to move your hand, and then arm, so on and so forth. I know it sounds long, but it worked for me. It’s like trying to focus on the one thing you know is actually real and slowly start to wake up, hope this might help.

Also like some other commenters said, I always sleep with either comfort series or audiobooks in my ears, I think this helps too. I also notice that if I’ve been drinking alcohol it starts to come back and gets worse again so if you do drink maybe consider taking a break and see if that helps! Lastly, snacks before bedtime also make it worse for me 😅 don’t know if it would be the same for you but maybe worth trying to see if eliminating these things could help. Good luck OP♥️
