I'm scared of a horror movie, what should I do?

I have the following problem:

I was with her at home, alone. She said we're watching spooky videos. Actually, I did not want that! But I could NEVER say NO because I have mental problems and everything is embarrassing. Anyway, I had to watch this with me

That was 3 weeks ago, I still have anxiety and I cover my mirror at night, do not shut my door out of fear of demons.

Please help me, it's bad for days now, I'm so scared and have not slept for the last 40 hours for fear of dying

When YouTube shows ads for a horror movie on Netflix, I'll pick up my headset because I can't handle the sounds.

I need help.

Therapy has never brought me anything

Information about me:

+ I'm 13, in 4 months I'll be 14

+ I'm highly sensitive

+ Female, please do not go to the topic, women are more anxious because I can't handle the issue of gender roles, and I do not want to be stamped

I think the description is enough

You should keep looking for therapies, one that really helps you. Brightness reduces the fear, also someone should be with you! If that does not help, I would do it with medical help to make the anxiety / insomnia more tolerant.

Ps: what about your environment someone who stands by your side?
