At the very least, stick with your thrush medication. You might be dealing with the big stress of the attack and some littler medical thing, and you are so freaked about the possibility of HPV that you are letting the big stress of the attack transfer to that. It happens.
I would read the link and see about probiotics also. Good for what ails you.
All you have said besides that your body is "not right" is that you have itching, burning and discharge. Those things can happen from any efforts you made to clean yourself up or out since the assault. Sometimes people can get sort of wrapped up after a rape in attempts to physically wipe it out, even when it is gone in the physical sense. (It is not gone from their mind, so they think it is still there physically also.)
Along with your attempts to get more testing to rule out a physical cause, why don't you seek out a counselor that knows a lot about treating OCD? Because getting tested 30 times and trying to commit suicide twice when you have little children counting on you to be alive, just because of three symptoms (itching and burning and discharge), is an excessive reaction. OCD is curable, and not too hard to cure either, and it does not take too long to cure, but it takes a therapist who understands the methods for treating it. You won't get untangled from the thought processes that produce it if you don't go to a professional who understands what to do. I am not saying you are wrong that something is physically there, but your reaction is very OCD-like even if it IS there. You need to find the right kind of help.
All doctors suggested it in my head and rush me along, even my psych just assumes that because of what’s happened. I though it was possible but now after 7 months and not feeling any better but no proper diagnosis I do feel like maybe I’m just crazy. But it does feel honestly like something is missed. The gyn did say high risk hpv can cause warts to and that I just have to wait to see if they come up, and they can only treat visible warts but itching and burning there’s nothing they can do. Yes I am seeing a councillor at the rape clinic and also a psychologist, I was still suicidal and called mental health triarge for extra help so I saw a psychiatrist and have started antidepressants. I was taking sleeping tablets and diazepam aswell as it was the only way I felt normal but have stopped the sleeping pills and diazepam as I was getting to addicted and now on antidepressants but I still feel like a piece of crap :( my body just doesn’t feel right- it’s the physical symptoms making me feel this way

Have you had counseling? I am not implying that this is all in your head, but the level of distress you are under is a medical condition also, and needs attention also. Suicide attempts are a medical issue and merit a therapist.
Ask the (ob-gyn) doctor to re-test you for anything that can incubate for a while and not show up on earlier tests.
Also ask if there is any form of suppository that can calm an upset vagina (and by this I mean one that has had its regular balance disturbed by previous treatments, douching, etc.). If you are stinging and burning, it sounds like your normal bodily secretions are disturbed, it's the kind of thing that back in the natural days, women would use live-culture yogurt to treat. There might be similar treatments today.
