I get that weird feeling that i don't like living in this planet. People who knows me wants me to change. I was a preppy good girl back then but things have changed. I started to wear something dark and I always felt depressed because of my past. I didn't want to be the bubbly nice girl anymore because I feel stupid when I think about that girl. Also I don't want to get along with people anymore. My family is so dysfunctional that I wished that I had a normal life. I don't want to change but I can if I want to.
Firstly, let me just say, I can relate to how your feeling. I've felt that way myself. And my family is also dysfunctional. So you're not alone there. But I think the main question here is,
do you really want to change? Not just for the people who know you, but for yourself. I mean, you said it yourself, you could if you wanted to. And, if you don't mind me asking, are you still depressed about your past?
I, myself, recently started getting counseling to help me deal with things from my past that I hadn't come to terms with properly. Now I'm not saying you should do the same - it's just a possible option. I don't know your situation but it might help you. Then again, you have to do what you think will be best for you.
You'll always find support here, though, remember that. And if you ever want to talk, you can always message me. Sorry, I can't be of more help to you.
