Body Odor for 3 Years!!!

Hi guys I have a long story. Ever since I was in 8th grade at the end of the year, I have received complaints of my odor. I remember vividly I was rehearsing my middle school graduation when a girl came up to me and said, "Did u shower today?" I said no, and I didn't really understand what she was trying to hint at since I had never got a complaint. The rest of that summer was normal, but once high school started, everything went down hill.
Everyday in Science class I would always be asked "did you fart?" or overhear someone say "someone keeps farting". It killed me mentally, I had many plans on killing myself everyday. The only thing that kept me going was my motivation to be successful one day. Even some of my best friends since kindergarten started saying stuff to me. Sophomore year of high school was better though, I received comments but much more infrequently. Now, junior year, the problem is affecting my everyday life. I've been to doctors and they told me to go to a psychologist because "it's all in my head" which is bullshit. Went there for 3 months, and I changed a bit, the thought of my odor wasn't on my mind every minute, but I know I still have the problem. People in my classes always cover their noses around me, ask what smells like a fart, etc. I've had at least 5 people over the 3 years tell me I smell like I just farted, so I know it's not in my head. I need to know how to fix this problem!!! I am an AP student that has dreams of doing something big in life, but I can't go to college with this odor. Everyday when i wake up, my room smells like stale farts and sweat. My parents room smells the same as mine which is quite odd every morning. I shower every morning, brush my teeth twice a day, use antibacterial soap, use antiperspirant deodorant, and occasionally wear cologne. Also, whenever I sweat, the odor worsens. Basketball, which is one of my favorite activities, is a struggle because I constantly hear, "who forgot deodorant" "I don't wanna guard him, he stinks" and constant sniffling. I'm truly on the brink of ending my life if I can't find a way to stop this problem because it truly affects me everyday and I can't handle it!!! Some background info about me too to help:
Rarely drink alcohol (like once a month if that)
Smoke weed twice a week typically (I stopped smoking for 3 months to see if that was the problem and it wasn't because the odor persisted)
Drink A LOT of water
Eat lots of meat
For the past month, whenever I poop, it hurts excruciatingly and blood appears on the toilet paper
Sweat makes odor worse
White marks on fingernails
Extremely dry skin (had it my whole life, not eczema though)
Smelly room in morning
I've been applying powder to my butt crack for 2 months to help with sweating, seems to somewhat work
And that's really it. ANY help will be greatly appreciated. Thank you very much if you have read this far! Tweet
