ibs has taken control of my life

i'm only 16 years old and i've had the worst year of my life.i never knew what my stomach/bowel problems could be and just thought it was what i ate..i was wrong. my mom has basically the same problems i do and she can't eat a lot of foods she would normally enjoy. my symptoms are diarrhea,constipation,bloating,gas,occasional pain and my stomach/bowels make noises if i have to go to the bathroom or my body is just a mess and won't shut up. actually today i had pretty bad pain and i had slight diarrhea and couldn't go to the bathroom. and of coarse i had to be somewhere tonight in a quiet room. i realized that ever since i've developed what i think to be ibs...i've also developed anxiety problems because whenever i know i have to go somewhere i get really nervous and worried and then my stomach gets all messed up again. and i can no longer sit in the middle of the classroom because i get panicky that everyone around me will be able to hear my stomach. so goodbye the next 3 years of high school because i can't focus on school work and do normal teenage things. i absolutely HATE how i have ibs because i could've had a boyfriend but i worried too much about if we were close my stomach would make weird noises and i can't eat normal foods because i worry if i'll have a problem. i can't go to the movies and if i do i barely watch the movie cause im worrying if my body will make a strange noise or whatever i eat will mess me up. ibs has taken control of my life and im done with it COMPLETELY done. i'm not going the rest of my life depressed because i can't do normal teenage activities like sleepovers and eating out and having a boyfriend. IT SUCKS. i know that i have to start to control my stress and do whatever i can to keep my anxiety low but i need more help than that. i need medicine. i heard digestive advantage for ibs might help or phillips colon health.. any suggestions? PLEASE PLEASE PLEASE help me, i want to start sophomore year with a new beginning and not relive freshman year. : /
