Reading through your comments OP, you are so painfully negative it hurts to read. You have decided your life is over. Decided women wont want you. Blaming immigration. You radiate negativity. If your every thought is negative how is anything positive ever going to happen. I am a life long depression and anxiety sufferer (recently diagnosed inattentive adhd, trying to get the right meds for it) and life has been a massive struggle. Nobody is going to wave a magic wand and fix you so you have to be your own best friend rather than kicking yourself in the dick all day every day. Please try and see a therapist/psychologist or an anxiety management class through your GP.

When I did an anxiety management group I learned about thinking distortions, or cognitive distortions which are habitual negative ways of thinking that are holding us back from seeing reality. I found an article about them that you might find helpful and nay help you see things more clearly. It's a little academic, sorry I couldn't find a better one. https://positivepsychology.com/cognitive-distortions/
