This is my reply from a similar thread, ignore the marijuana part:
If you're still reading this thread, these feelings are totally normal. I went through anxieties when I felt that too and I thought "oh no, what if I won't feel normal again?"
It tells you to just accept the feelings, and you'll just forget. It sounds easier said than done but just accept they're normal, and then you'll feel normal (because you won't be thinking about it).
A good example is if you think of your socks... you don't notice them at all, but when you think about them, you can't help noticing the feeling of it on yuor foot. It's the same as wearing glasses.
Obviously stop the weed, I've done it quite a few times in my mid teens and late teens.
But yes, it's just a form of anxiety and it'll go away. Read the link! It helped me.
