It started about a month ago. The thought that I will die one day makes me so anxious that I can't concentrate on daily things. I can't imagine what it will be like when my parents die and when me and my friends will be old. I can't imagine my best friend dying. This makes me cry every time. 

It's even worse since I want to do something about it, but I can't and now I'm just stuck here, knowing I'll die one day. I hate this. Everything seems worthless. I hate that we humans are aware of our death. I'd rather just not know.

Does anyone experience this?
