been to over 100 docters,no one can help...

Hi i have a very serious question,please do not respond if you are not in the medical field,i don't need people to guess' what is wrong with me. For the past two years i have been having itching in my vagina region and sometimes anus,as well as a lot of grey/white vaginal discharge. There is a strong smell in my vagina area,that more so comes out after i sweat.(such as getting done with a workout.) Now i have had a full panel std screening and everything came back negative. So things such as Chlamydia,hpv,Gonorrhea have been ruled out. One doctor told me maybe it was Trichomoniasis, and gave me medicine,It did not go away.I looked at the symptoms of pid and cervical cancer i do not have any of those symptoms,and i get regular pap smears,so i do not think i have either of those. My bf is  not very supportive.He has told me its all "in my head"BUT... i have been suspended from my job,because the boss could "smell " me and there were complaints from customers. This has absolutely ruined my life,i can barely work,i started eating a lot to help my depression(and gained 30 pounds because of it.)i wouldn't say i am suicidal,but i do wonder why anyone would want to live, when they have to be the laughing stock of their job. I have considered maybe i have fish odor syndrome,but there is really no doctors that test for this,So i have no idea if this is a possibility. I have noticed that my ph level is elevated,tends to be higher then normal. I have peed on a stick,and it told me my body was more alkaline.I also have ibs,although i don't think has anything to do with it.I am only 25,i have been to more then 100 doctors,and they all have said either i am crazy,or all gave a different answer of what i might have,they all seemed more like they wanted to push me out of the room,so they could get to their next patient.Can anyone please help me?
