Opinions? Advice? Help?

I needed someone to tell this to besides my best friend so that's why I came to you guys. I've had a slight weight problem throughout my life and it has really been rough. During the past school year I lost 30 pounds but not in the best way. I hid everything from my parents. I skipped breakfast every morning, which they actually didn't mind because they thought that it was fairly normal. I also skipped lunch everyday. Whenever I came home from school for supper I hardly ate anything. I felt really bad about my mom giving me lunch money so I told her that ';I would pay for it myself';. I also worked out so hard during my Phys. Ed. class on an empty stomach since it was right after lunch. Even though I did lose a lot of weight I still see nothing good in myself. I hate when people give me complements about my hair or my clear complexion because I hate hearing good things about myself I guess. I still want to lose more weight. I talked to one of my best friends about this and she thinks that I may be going through depression. I have a lot of the symptoms like neck and back pain. Another one of my friends pointed out that I was very pessimistic and I know that it is true. My parents don't assume that anything is wrong with me except for my hatred of my weight. I also have started doing terrible in school all of a sudden. I was making straight A's and then this past year I made a D in Geometry and an F in science! I really want to boost up my self-esteem, start doing good on my grades again, and begin to accomplish all of the things that I have always wanted to in life.





Of course I haven't told you guys everything that has happened in this situation. I actually still have worse things hiding deep down inside of me, but it would be nice to get some advice or something about this.Opinions? Advice? Help?
You are so concerned about losing weight, but you haven't said what your height and weight are. I think you may be anorexic. Tell your parents. You need help.
