I think I know what it feels like to be a failure from the viewpoint of a failure.
Are you saying you feel like a failure?
Yes, and it makes me feel really uncomfortable.
It's not good to be so down on yourself and call yourself; it just reinforces negative thinking and you'll feel even worse over time. You should talk with a therapist in order to work through the issues you are experiencing and learn strategies to lead a happier and healthier life.
So I need a therapist and you know what is best for me? Oh well I'll do it anyway.
It's okay to need a therapist, most people would benefit from having someone to talk to that will actually listen and provide helpful feedback. This can help you to stop labeling yourself as a failure. It's a hurtful and unproductive way to see yourself.
