Living with my parents is a nightmare

Hi. I know that I haven't been on this website in months. But now I feel desperate for help so that is why I am reaching out to this community. If any of you recall, I am living with my parents. I have graduated from college back in May of 2011. I am living at home because I don't have a full time job to support myself on my own. It is not however, that I am sitting on my ass doing nothing. I do work part-time at a nonprofit organization, which has been going quite well over there. I am also trying to create my own life outside of my family by using meetup.com. That has been going well too.

However, what it really taking toll on me now is my living situation. I grew up with parents who definitely loved me and supported me, but were constantly on my tail about everything. This could be my choices in life, my clothing, how I socialized with people, what I ate, whatever it was, they always knew about because they were overprotective of me. It all comes back with a vengence when I start living at home. It has been taking a toll on me and quite frankly I do not know what to do anymore because I don't have the energy to fight with them. The only things that I have energy for now are my current job, finding a full-time to replace my current job, and having a life outside of parents. But apparently it seems like every time I take one step forward, I eventually take two steps back because my parents don't seem to approve of what I am doing. I hate having to spend the energy thinking about their approval on things, but I do because I am worried about the aftermath because I have seen it all before.

I just now feel lost and unfulfilled right now; but I mostly feel unhappy. I am trying to read this self-improvement book called "Feeding Your Demons", which I have started reading. And I want to get started with the actual process but I don't feel comfortable doing so in my current environment. I tried to continue to read again today, but my dad decided to lay things on me about what I am not doing right. That got me into this whole self-doubt feeling and I broke down. My parents didn't see me break down (thank god) because I did so while they were out. I broke down because it was just another one of those times where my father had picked at my thoughts and telling me what it is that I have NOT been doing according to his standards.

I hate that I have to live by my parents standards because that is just pissing me off the most.

I just need help here and want to ask if i am crazy to be thinking this way or having these thoughts of unhappiness and self-doubt.
