I can’t stop feeling afraid of death and disease and catastrophic injury…
I am afraid to die, even though there’s nothing that says i will any time soon. I’m terrified of paralysis and it makes me sick to think about. I’m afraid to be permanently, disgustingly scarred. I’m terrified of becoming an invalid. Especially of being stuck being cared for by my dad or stepmom, or losing my freedom. I’m terrified of getting a devastating disease.
I can’t stop feeling scared even though there’s nothing to worry about right now and I don’t know how to make it stop.
You're not alone. I work in Psychiatry and I've seen similar things before. Have you ever considered counseling? If you don't feel comfortable seeing a counselor face to face, you could always start by finding online support groups. You'd find people who can help you and give you advice on how to deal with this. You don't have to do it alone. Good luck :)
Ever heard of Hedonic adaptation? If it can help you feel better to know, people who have life changing events, like those you mentioned, after some time go back to how happy they were before it happened. You are afraid of things, as they currently are, changing, so to a point you must like your current life, if anything happens, you will get to like and adapt to your new life. But do talk with someone about where this fear of uncertainty and helplessness comes from.
