The best advice I can give you is believe in yourself. You are worthy of anyones time if you believe you are. You dont need anyone else to jsutify your existence. Just be yourself and you will make new friends. You may find that the poplar people may not have the same values as you and you may not want to be their frien. Be yoruself, the rest with work itself out.EDIT: As far as losing weight, try something simple at first like not drinking any soda, just juice, 100% juice. And no fast food, or fast food once a month. Combine that with a simple exercise routine like walking for 30 minutes a day is very good start.
hey im in high school and i know how you feel try playing more sports and eating less sometimes after people go through something tramatic(the divorce in this case) people turn to different things to make them feel better like food and tv. yes im sure you have heard this all before but some people just dont notice they are doing it. Also try hanging out with the cool people getting to know them. and if that does not work and you are desprete try wearing clothes, playing sports, or hanging out the places they do. but dont be stupid and start smoking, doing drugs or other stupid stuff i know it sounds uncool but you will regret it later. hope all this works for you. Good Luck and enjoy high school it s awesome!
