Is it normal i think like this

You might benefit by trying to help others that may not have the ability to help themselves. You can go to homeless areas to help serve lunch, etc. or even go on a trip to another country where you can help build shelters or serve in some way for a few weeks. Believe me, you will learn a lot and will not have the feeling that you need help from others. Just try it once, probably through a church, where they have the contacts.
good luck. Remember, you are a good person, make the most of you life.

I have a similar issue. I find that watching scary things makes it really bad. Maybe after watching the scary movies, either pray, if you're religious, if not, then find something funny to watch afterwards, or something comforting, like pictures of kittens.

And really go into depth with your therapist about this if you can. If it's a big issue, present it as so. I hope you feel better soon! :)

Maybe you should seek some religious guidance.

Also, and this is just my personal suggestion, maybe lay off the weed pipe a little. Just a little.

Have you asked your therapist/psychiatrist whether it's normal?

The stuff you say about thinking too much and making yourself believe there is something wrong with you sounds like OCD, to me. Maybe it could sound like something else, but I have more familiarity with OCD.
I'm not suggesting that that has anything to do with your case, since you have a therapist and a psychiatrist to tell you about your case.

It isn't normal to throw up from fear of getting possessed. Perhaps you should keep off the 'scary movies' for a while.
Best to steer clear of any supernatural stuff, so I really wouldn't recommend visiting a median for help.
