But I am sometimes hesitant about heights due to an inner ear problem. (If I don't have to worry about getting vertigo and falling, I like being up high.) As they say, "I'm not afraid of heights, I'm afraid of falling!"
Emetophobia. (Vomiting) It's I think the fifth most common phobia, and it's really not fun to live with. It's changed my whole life since I was a kid. Sometimes people that are just scared of something call it a phobia, when in reality phobias are intense, irrational fears that cause people to run screaming from whatever they've got a phobia of. Phobias suck, because in reality we know our fear is stupid, but our subconscious mind screws us over regardless.
Arachnophobia. I also have a pretty serious irrational fear of bleachers and open staircases that are found on a lot of apartment complexes. It's a real chore trying to get me to go up or down those stairs.
I also have a pretty crippling case of phone anxiety. It's been interfering with my life for quite a few years but I wouldn't call it a phobia.
I have a pretty severe phobia of fish and whales (specifically the gaping mouths). It's a topic of joke in my family but really interferes with day to day life sometimes because even images of whales or fish can cause me to panic.
