I had similar thoughts as well at first. I chafed against the effort involved in dressing better, being more sociable, and a whole range of other habits. The surprising discovery I made in that case was that I started to like things I previously disliked (certain types of social activities) and lost interest in things I previously spent a lot of time on (mostly escapism). As I engaged more with the world my attitude changed, even though I retained the same core personality. I effectively passed a threshold beyond which the effort started to pay off in terms of satisfaction, to the point where it no longer seemed like a burden at all.
Of course, this is only my own experience and will not be relevant for most people. However, it's certainly a counter-intuitive notion that merits investigation. At the very least, it's quite helpful to critically evaluate your most common habits and patterns.
It is oftentimes limiting too much - their expectations costs you. I get what you are saying and that it works that way, but it oftentimes forces you to pretend you don't like things you like or to avoid things you would like to try. I mean, yeah, they would respond to me better and I would have more meaningful social interactions, but the cost is too much.
