Hi Reddit. I'm 15 years old and have been diagnosed to have GAD and depression for 2+ years. I have been prescribed 100mg Zoloft for well over a year. It's come to my attention more in the past few weeks that I often talk to myself and/or others in my head. Sometimes it's as I wake up, sometimes it's in the middle of the day. Sometimes it will be me speaking to someone I know or even someone I don't know, but more often it's other people talking and I'm just listening: I'm not even in my mind anymore, it's just these two people talking about random stuff that I honestly have no idea how it got in my head. I've never been told to do anything by these voices, so I don't think I'm crazy, it's just been getting on my nerves recently. Any time I try to focus on the conversation it just goes away and that is what I think is the most annoying thing to me since I can never really remember any of it once I notice I'm doing it. 

Another thing that was brought to my attention (and this is something I've been doing for over 4yr) is that when I'm watching a movie or video I find myself quietly repeating words that are said. If I'm not doing that, I'm making a humming noise in the same pitch of their talking or just weird noises in my mouth that almost resemble a throat kick (a common sound in beatboxing). This could be completely unrelated, but I wasn't able to find anything online about this so I was wondering if anyone here had any answers or know anything of it. 

None of these things are 24/7, but they definitely happen daily. I notice it and can't seem to stop. Any advice or anything really is much appreciated. Thank you. :)
