I probably said this before, but one of your issues is not being a "social leader" and being a little too self conscious.  You worry too much about other people's perception about you and you like to hide certain aspects of yourself (out of worry that it might damage the perception others have of you).  It's a bit of a mental task, and you'll really have to find the optimal solution, but try thinking that others really don't care about you so much.  I imagine you do care a fair bit about what others do, so it might be difficult for you to accept that others may not consider you as so important.
Think of it this way - so what if they think you like watching anime girls?  They'll probably think you have weird tastes, but if you're a good friend, they'll easily overlook it, after all, I doubt they're thinking that you'll do anything "weird" to them, so they have little reason to dislike you on the basis of that.  Don't be ashamed of what you like (note, not suggesting you like it, but if it's the general perception of you, just go along with it - you do enjoy anime don't you?) - there are people out there with much more bizarre preferences than you.
