Has anyone ever had a sleep paralysis?

I've had 2 before about 10 years ago, and recovered from it within 2 weeks.
I've had another one last October, and I basically haven't slept since then. I'm exhausted. I fall asleep about 4am, until then I just lie awake being scared.
I'm perfectly fine when I'm at my parents for the weekend, but I can't always go there as they'll start asking questions to why I'm there so much, and they won't understand.
There's no one in my appartment, no one can come in here, building is secure, I live above a bank. Yet, I keep thinking with every noise I hear someone is inside, because hen you experience sleep paralysis, someone is inside and touching you. So I just lie awake for hours.
