Drained

I can relate to this. It sounds like you had a really severe panic attack ): Especially with the rapid thoughts. Do you think something in the environment may have triggered it? Sometimes, I get triggered by something subconsciously and start panicking and the symptoms I experience are on par with what you just described. In those moments, I can’t even identify what upset me, why I’m upset, etc. If you have the energy, try to brainstorm and see if you can pinpoint a trigger. If not, it may have just been a spontaneous anxiety attack (a really fucking awful one from what you’ve described). I hope you experience some relief when you wake up.
