Sleep paralysis driving me crazy?

I used to get it like once a year but now i seem to get it more and more often. It used to be that i woke up and couldnt move and felt an impending sense of doom and heard breathing (which was probably my own). Sometimes it would be that somethings in my room and i get up to go out the room but suddenly im back in bed again because of course i havent got up at all. But now i get it even more vividly where i can feel something attacking me, sometimes ually. I know that there is no one there because seconds later i am awake and there is nothing in my room. Tonight i had it 3 times in a row where i was asleep and something was on me and i could see my hand in front of me and i thought it was someone elses as i was trying to touch it and i felt nothing, then i rolled over and was looking at myself sleeping and i tried to scream for help, then my cat luckily started itching herself and it shook me enough to wake up properly, anyway i was so tired i fell straight back asleep again and the same thing happened again and something was saying that i couldn't get away and it started attacking me again. I know i was awake because i could see my hand and in front of me and i didnt fall asleep like that. I am literally struggling to keep my eyes open but i can't sleep because i am too scared. I know it is (probably) nothing paranormal but it still freaks me out
