I think my inner voice split off and became someone else and I’m not high

I’m 16f bmi 18 and I take an inhaler and sometimes I smoke weed

A couple days ago my inner voice, like my thought voice, started whispering. Like the voice I think in. It got really quiet, and sounded far away. I couldnt seem to turn up the volume. I tried to imagine it shouting but it was still quiet and it was hard to hear my own thoughts. It stayed whispering until last night when it was normal again.

Today though, the thought voice is different. It doesn’t sound like me anymore. It sounds completely different and I can’t tell what it’s going to say ahead of time anymore. Like I don’t know my own thoughts. It’s like it’s become its own thing but if I tell my mom she’s going to think I’m high and I’m not. I swear I haven’t smoked in like a week. wtf is happening why is there someone else’s voice in my head now if I’m not smoking? I can’t figure out how to make it leave.
