I gained 30 pounds within the last 2 months, I don't know why I just did. At first I thought I could work it off and everything would go back to normal. I kept gaining and became ashamed, I started not leaving the house I deleted my Facebook and email. I cut myself off from all my friends and I have hurt so many people, I hate myself for it. I just don't want anyone to see me like this, none of my clothes fit but Im too embarrassed to go out and buy new ones. Now I just eat to fill this hole that's inside me, I cry almost every night and don't know how I can get out of this. What can I do to go back to my old self I don't know how to get my self-esteem back.
