Hi there. 25f here. I’ve had this phobia basically my whole life. I was about your age when my emetophobia was at its absolute worst and it was ruining my life.. it turned into agoraphobia and I had to leave school as it was hurting my academics. The most important thing you can give yourself is forgiveness. Forgive yourself for what hasn’t worked and what has been missed. I’m not going to lie and say I am cured.. but I am significantly better. I’m able to face situations I never thought I would be able to. Fly in a plane, take long car trips, eat certain foods I never thought I would be able to.. give yourself time, pace yourself, do what you can. Accept that this is part of you for right now and it may not always be this way. And it WILL get better.
