You’re correct. Your anxiety is still with you. At this point, you are scared that you are going to be scared, which makes you even more scared. You have a vivid imagination so you’ve come up with “characters” that make your fear make a kind of sense. Now they have taken on a life of their own.
You’ve already done the kinds of things I would initially suggest for someone like yourself — superheroes, a barrier, having someone sit with you, etc. None of them are working. It’s okay to admit that to yourself. Anxiety is often too difficult for a person to manage without external help.
So the next step is to see a counselor who specializes in anxiety disorders. Anxiety is very treatable. A combination of some medication (at least for a while) and talk therapy to help you better cope with the anxiety is probably what you need. If you were seeing me, I’d probably suggest some cognitive behavioral strategies and maybe some self-hypnosis as things to try.
I’m very glad you wrote to us here at Psych Central. Reaching for some help this way is an important first step. Now, please: Take the next step and ask your mom to help you find a specialist to help you address the anxiety so you can enjoy the rest of your teen years (and the rest of your life) without feeling constantly threatened.
I wish you well.
