Do you think it is weird that I'm afraid of a cartoon?
What kind of cartoon? Do you have a certain memory related to it?
It's just that, a Doraemon cartoon. When I was a kid I watched it on TV until I was about 12 or 13 years old.
While being scared of a cartoon is unusual, it's good that you are able to admit your fear to others. If you are unable to move past it yourself, you should work with a therapist so that you can get over your fear of Doraemon.
From that point I was able to move on and don't watch this show anymore. Although some days later I was still scared of it I couldn't explain why.
You can be scared of things, and that's fine. I'm glad you've not watched it anymore since it scared you, now you need to just move on since you know what the fear is.
