I suffer from anxiety and its just about as bad as depression. In fact I have to fight my battles or depression is the next stop. So if its any consolation you are not alone in fighting inner demons. I know those "reassuring" words do little to relieve the suffering. What I will say is when it comes down to the nitty gritty, you are the one that has to fight the good fight and regain control of yourself. No one else, not even your friends can fight those battles for you. Stay strong and when the load gets too much fined some comfort on the shoulder of a good friend or mate. Also don't be afraid to seek outside help like a Psychologist. There is absolutely no shame or weakness doing that. When I fond myself fighting a losing battle with my anxiety and ended up in the ER over it, I sought out outside help. It was the best move I made in a very long time.

That it accomplishes nothing?
That no-one cares?
That the world is systematically programmed to only think of themselves and slave for the system?
That it's all business?
All of the Above?!
Been there, Understand that.
