I can’t stop worrying about shit. I get so afraid before doing even basic tasks like even emailing someone or making a phone call that I end up not doing it and it fucks me over horribly.

How do I get over this bullshit? How do I stop fucking worrying about everything? I’ve already wasted over half of my 20s doing this, there are so many doors closed and opportunities lost to worry. How do I stop feeling nauseous and stop my heart from pounding in my chest when I try to go outside but hear someone just outside the door? How do I stop being afraid to send emails or make phone calls?
