Baby Doll, take one day at a time. Don't look too far ahead, and yes a goal or two are helpful.
2012 has been a s h i t t y year for me too hun. Lets hope and pray 2013 is happier and more fruitful. My goals are to get out of bed and stay out of it, get help, lose weight, get my hair done, nails done. Get a new job, get a life basicly.
You need a vision to succeed, achieve, small baby steps not leaping forward. Maybe a plan to ease your day to day living, especially if your brother leaves home.
Would you perhaps pursue an online study of some sort ?
What help can you get to help you physically ?

Well slap me down for being positive, but doesn't 'The Lord help those who help themselves'

I need to take my own advice but to a friend I'd say, take it slow, a new year, new plans. Maybe nothing huge, but small realistic goals.

You are young Hun and there's a whole world out there !
We just need help to reach it sometimes, but we shouldn't lose hope.

New year, new hope.
