Hi again, @TomRiddle32
I have bipolar, with major depression and anxiety being the main symptoms over my life.
When I was at my most depressed, I remember being at a Patty Smith concert, an incredible artist, but I felt so horribly distant and untouched by anything I was hearing or experiencing. All I could feel was being swallowed up by my own depressive misery, all alone with it, unable to be reached. If what you experience is anything like that, I know it's awful and hope you are able to put this past you soon.
I still struggle with depression after a very long time now but I almost never experience anything as bad as that. There is hope for a better future.
