I need to get up for work in a hour and I can’t sleep bc my anxiety is through the roof

I don’t know why. My heart is racing, I’m trying to quiet my mind, but when I try my thoughts are all over the place. I’m panicking for some reason, I’m forgetting something or someone needs something or I’m letting someone down idk.. I suck, I know I do. I need to do better and be better. I don’t know wtf is wrong with me. I just want peace. I spent my life being a quiet little thing in the corner nobody noticed, I valued the silence.. but now it never stops, everyone always needs something, but why from me? There is always someone better, smarter, why not go to them? I’m so imperfect, boring, the furthest thing from beautiful, yet everyone keeps coming back to me more and more. At work, at home, everywhere now. I never set out to lead, but everyone keeps following me. It terrifies me that so many people think I’m their best chance for guidance, for help.. how sad is that? I’m always honest about my shortcomings, I don’t hide them, so why do people keep thinking I’m more than I am??? I miss the days when people just accepted they were better and didn’t pay any mind to me. I’m tired.. I’m sorry if you wasted any time reading this. I’m logging off now to try to sleep.. I just needed to say things I can’t say out loud.
