In my head

I feel overwhelmed by everything these days. What is wrong? There are so many thoughts in my head, I feel like someone is stuffing their junk into my head, pushing it further and deeper into it, like their life depends on it. My brain absorbing everything, every single thing and then throwing it out again. It never stops, there probably is no end to this, because as long as I'm alive my head will me a big ocean of useless thoughts.
