Anyone else feel this way or am I strange?

I don't know if anyone understands what I mean but when I leave home and get married (if ever) I feel like I can never be/do what I truely am. At home with parents I can totally be myself and act childish if I don't get what I want and do what I feel like. I have anxiety and its hard to express this as an adult living with a family because you can't just sit down and start complaining (which is what I always feel like and end up doing ) you have to continuously get on with things and I coudn't do that. I have these moods where I feel weak and sick and just end up lying down for ages or daydreaming. Again you can't do all this as a mature adult you have to 'grow up' and keep going and I don't know how people do. The problem is I am an adult im 20 so im not going to naturally grow out of what im like.

Is anyone else like this (as in has these weird moments) or is no one else like this?

i'm guessing your a girl? and yeha ul just have to get used to it. the real world is big and tough, u need to appreciated that you have to work for stuff and accept you can't always get what you want. on the other hand i think u can expect people to sympathise etc, u just have to be careful about how you go about getting the sympathy, sitting on the floor and lyring around for ages is not productive. talking to people is, whatever your age you need someone to talk to and vent stuff to, but erm acting childish in the adult world isn't the way to acheive this.

Whoever said that being 20 makes you grown up? I'm just over a year younger than you and I can't see myself being that much more mature in that time! I fully intend to be as immature as possible for as long as possible. If you think about it, you only truly grow up when you're placed in a position where you need to, like moving out properly or having a responsibility like children. Don't worry!
