I am constantly around people. Feel like I might break... Does anyone else feel similar? How to cope...

You really shouldn't lie about your age. How can anyone believe you are as old as you claim if you still live with your mom and she ruins your life?
You NEVER have to answer a text message if you don't want. Get out of your room and out of the house-- go for a walk. Go to the library and study. Go catch a movie with a friend. If you are as old as you claim, finding things to do away from home wouldn't be so hard. You certainly wouldn't be talking about your mother locking you in. What's up with that?

I do feel it alot
but sometimes u need to dement ur time for urself,don't let people to write u when and how to managed ur life, after all its ur time,not them
if u do care about them,then yeah speak,but u have the right to just get away of everything,in my opinion u should go to read a book,write a diary or something in ur blog or i don't know , just lock ur door, or go out side and do a long walk .
or just say - I don't have power for it.

Why can't you have "me" time? Do you have no room of your own? Can you not take a walk if you'd like?
I used to bury myself in books sometimes. Or just go outdoors and sit in a quiet corner. Just a moment or two to clear your mind can help.

im trying to understand..sorry, but you really cant leave your house? ever? i read thru the messages and i didnt see you give a direct answer to that..does your mom actually lock you in?

ugh i would go crazy with out me time. NONE
LOL go lock yourself in the bath room, take a hot bath, w/ no phone
