situation "A": Your parents control your life. If that's the case, you kind of have a problem. But, usually in this situation there are certain advantages that other don't have: maybe they don't let you go out much but they buy you a cool audio system (for example) or something similar. Maybe they let you call your friends at home a lot. My advice is to find an advantage and take the credit for it.
situation "B": You feel like you don't have any real friends. Well, then you have a serious problem. It's hard to know there isn't anyone to give you a friendly hug, a person with whom you can be sincere but I'm sure you know better than me what's it like. Good people are all over the world, even if you don't believe me. You can find a friend from another country, you can share all the secrets without the fear that he'll tell, but one day this won't be enough. Time to get out in the world, alone, and search for a sincere person who would like to spend time with you. It's going to be a long ride, because friendship doesn't form in a few days or weeks, sometimes it takes only a few months, sometimes it needs years. If you're part of a group (even at work) it's good to see if you can have a special connection with someone around there, because it's good to share most of your time with a friend with whom you have the same interests. I could talk all day about friendship, but if this part of your life is missing you better do something now, because later you'll regret. Oh, and you can keep your fake friends too, they're good when you are bored at home and don't have anyone to go out with.
situation "C": A lot of things are happening in your life. You're an over-dramatic person or you don't have a choice but to be one. You make a scandal even out of your smallest problem. Make a list of the things that are ok in your life, and the ones that are not, and change anything you like slowly, without telling everyone a thousand times a day what is happening or what happened. I'm talking here about the people who want to change this lifestyle. And, if you have a life like in Gossip Girl, then, my sincerest congratulations, because you have an interesting life that's filled with a lot of events, and people and friends, and love and everything you wish for or not. If you're like this crazy girl/boy with a lot of popularity and you think you got bored of it, trust me, you're not yet. It takes a lot to imagine the perfect life in the perfect conditions without getting bored, but the hardest part is to actually live it. So, even if you're exaggerating things what matters if you're living them.
That's the problem with people: they don't know when to stop dreaming and start living. So, no matter who you are, what you think you are, live for the dream! And trust me, when you want something there is nothing that can stop you, but your own personality and thoughts. So, if you want to blame someone, the only "criminal" is you.
There is a quote from Dollhouse, a very interesting TV series that says: "She's living the dream." "Whose dream?" "Who's next." Make sure you're living your dream and not anyone's else.
