Okay,
the truth is that this is probably the toughest age to be in, I know and can probably remember 14 ad surrounded by pretty people,
Its hard to do but you cant take yourself too seriously, you have to know that depression and overeating are bedfellows.
My solution and trust me I am no expert, heck I am a mechanic!
is to travel i new circles, force yourself to go chorus at church, good idea at least the church part, try new activities in school, and that guy who has not called. well take the initiative and you call him! dont be desperate just ask him how is everything and maybe invite him over to church or family picnic or whatever is going on.
Tell yourself life is just a bunch of little victories, you wont win them all but give it your best.
About the weigh, well honey I have been up and down in my life it takes a lot of determination and support to lose weight, but I have found out that when I am happy it seems easy to stick to it, instead of laying in bed with a stack of junk food, I went and helped feed the homeless, then I went to help build a house for habitat for humanity, Offered to help paint a house for an elderly neighbor, and right now I came in to cool off because I cant seem to fix this old mans lawnmower!
Good Luck God Bless and never ever ever give up...... you are worthy!
