I feel that our looks and appearance are a great part of what makes us our "real" selves. What is seen on the outside is a reflection of what's happening on the inside. It's ok to look and feel good.
I don't hang around people that want to "possess" me.. If I ever pick up on that vibe, I quickly make a switch..
I once read that "equals become friends." When I read that, I thought a lot about the people that I had been hanging out with, how they influenced me, and how I influenced them. I reccomend that you do the same.
I feel that being an adult has little to do with the amount of friends you have. I feel that it's a mindset - a personal choice. To me, being an adult is defined as "the ability to have fun while being responsible." As adults, and as sentient beings, we are responsible for our individual selves. This responsibility includes our mental health, our physical health, our sexuality, spirituality, and the way we treat others.
These days, I'm learning a lot about myself through the people I once regularly associated with. I've picked up a lot of traits from my friends - some good, some bad. I realize that it's up to me to change these habits, or to live comfortably with them. Either way, they're my habits, I make sure that any judgement I feel about them is my own. If I feel that someone is attempting to make me feel guilty about being myself, I stop associating with that person. I choose to surround myself with good people. I choose to think and execute as a good person. It's like excersizing a muscle - start slow, stay slow, become strong. "
