yes you are safe from going blind. you have to understand that your anxiety is creating this thoughts and that while they feel very real they are unrealistic. that doesn't mean you are going to stop feeling them. there is a stigma associated with mental illness and other people just cant understand what we are going thru. they just don't get it. they will never get it. like people cant get that I am afraid if I walk out the door the sunlight will vaporize me into a cloud of dust. this feels very real to me sometimes. other people think it is ridiculous. they look at me like I am stupid. this hurts me. so I have learned not to tell people because I don't want my feelings hurt. I don't want people looking at me funny. you have to learn to only tell people who are supportive of you and understand.
