Does anybody else have this problem???

For a while now, years I guess (I can't remember when it started) I am constantly thinking way too much about others'thoughts instead of my own, for instance I base the music I listen to off of what a couple of my friends listen to (and the guy I kind of like) which has been partly a good thing (I started listening to some really great music that I love) but I am constantly thinking: "Would this band/song be "acceptable" to ___?" And it really drives me crazy because I want to be able to have my own opinion without being bothered by these thoughts that I have to be living up to other peoples standards! And I know they are unreasonable thoughts, but I can't seem to shake them and it leads mt to feeling, not exactly guilty but just not good enough, when I listen to the "wrong" music, like "if ___ wouldn't like it I can't listen to it because ___ would look down on me for it". And I don't want it to matter to me, but it does!! It matters WAY too much!
And also, along the same lines, for a few years I have had these thoughts like, "if ___ were here right now would he/she approve of what I'm doing?" not like a conscience thing, like am I doing the right thing, more like what I'm wearing or doing or watching or listening to, would they think it was "cool"? To the point that I almost feel like they are there, I mean I don't believe it but I feel pressured to be "acceptable" to them even if I'm by myself. This could be partly because I have imaginary conversations with people that I know, and so I kind of feel like they are there. But I don't think they are there, its more of a silly what-if thing but my brain takes it way too seriously! This BOTHERS me and I can't make it stop! I constantly feel pressured to be accepted and do the "right thing" for people who aren't even there.
I hope this made sense. It's kind of hard to explain. Does anyone else feel like this??? Is this a problem? Could it be associated with some sort of mental problem? (I have depression and social anxiety problems)

Hi Mylifeisdepressing; Don't let peer pressure take over who you are. You must be yourself no matter who you are with. Other people's opinions are NOT more imporant than your own. You don't have to change for other people. You are in your own skin and the only person you can be is yourself. Get a better sense of who you are and you are as worthy as any human being in this world. Feel the POWER of being your own unique being. Hugs

Thanks...but the problem isn't that I really think other opinions are more important... It's just that I can't make the thoughts go away. I know they are unreasonable, but they're always there, and I can't convince my mind that they don't matter...
