Don’t.
Embrace it. The more you fight it, the stronger it gets. Feel it fully and then act despite of it. Don’t let it hold you back.
Know that all that it is is a feeling. It’s not a real threat. It’s a feeling that doesn’t define you. Separate yourself and your worth from your automatic thoughts and feelings. They were put in your mind by the last TV commercial, your parents, or even your best girlfriend.
Anxiety often is a result of perceived pressure or expectations – mostly from yourself (because even when you think that it comes from someone or something, we ultimately decide if we allow it into our lives). Free yourself from these expectations and replace them with love and understanding towards yourself. Know that you do the best you can and that it’s okay to “fail” or to “disappoint”. You weren’t born to be perfect, or to live another person’s life, but to live your own with all the good and the bad feelings that come with it.
