I hate my anxiety.

I really wanted to sleep tonight but every time I closed my eyes my mind questioned physics and how the earth works and why I will never be a bird and why I can’t regain those minutes I just spent worrying about everything and how I could die at any second and will I be saved or condemned and how any one of these thoughts could be my last thought and I need to be picky but is just cycles downwards until I am just terrified I am going to die any second and I am on the edge of crying so I just get up and get on Tumblr to avoid it all but I am so tired.
