so lately I'm going through an anxiety phase, and at the moment I'm often getting false feelings of guilt, over things like stuff that I did for no reason but on hindsight seems weird. Not only that, but unpleasant thoughts are doing the rounds in my head, and it can make me extremely anxious at times. Even if I try distracting myself, the anxiety remains. What can I do to be rid of the false guilt and horrid thoughts.
