Late 3 am thoughts

I was overwhelmed for past few days. And every time that happens, Lord knows how much I get to suffer from existential crisis. it's 3 in the late at night. I woke up at 11 pm. the feeling was there still, swallowing the crap out of me. And then suddenly I felt something got down from my shoulder and the world feels heavy no more. Is this what they say that on a Monday morning, you just know you're alright? I don't know how long the peace would last but all at once the life's worth living again. A lot of things on my mind right now but they don't weigh me down anymore.
