fecal odor

I used to be considered really skinny so I started working out and nearly tripling my serving amounts of protein and carbohydrates at about 19. After bulking up I noticed that the chicken/steaks/and protein bars would really leave a bad fecal odor in the restroom. Soon the smell began to come from me while lifting weights and playing Racket ball, so out of fear I stopped going to the Gym and changing my diet.
I decided to cut back on red meats and eating whole grain foods, but the fecal odor persists. Throughout my life the smell comes from me if I sweat or get nervous. Now I’m 25, eating according to an IBS diet with chlorophyll and I still get people making comments about me. The thought of going to Doctor used to scare me but now I’m losing myself to depression. Has anyone gone to a Doctor? Do they take your symptoms seriously?
