help!!!!!!!!!!!!!!!!

Ever since I was in 7th grade I started getting complaints about me smelling horrible. I'm now in 11th grade and still smell just as bad or maybe even worse. Nothing works! I bathe regularly, I brush regularly, and I scrub every inch of my body. The odor just won't go. I take showers before going to school and it's really frustrating that even though I bathe properly the smell is there. I'd do everything imaginable to get rid of this. Very occasionally I get a whiff of my smell and it's absolutely horrible!! My family nor my friends ever told me I smell bad or anything...they even say I smell good! I apply deodorant of course and it just seems as if with all these attempts its just useless. I must admit that I do not foster a healthy diet-- I eat curry (I know--horrible!) BUT either way if I don't, I still smell just as bad. Just yesterday, some girl was saying "she smells bad, everytime she walks in the room it starts to smell" sometimes people even move away from me cause I smell so bad. It's really hard to be myself if I'm being shut down by my odor. I just wish people would get over it. This has even led me to have suicidal thoughts and it just sucks overall because I know in the future it'll be really hard for me to get a good job or get into college if I have "bad hygiene." If it helps I am 5 3 and weigh 134 lbs and do not take any medicated nor illegal drugs (occasionally marijuana).
