cin3 colposcopy help

Hello :)

I would love some advice as it’s so difficult to get details and having to wait for letters and appointments is awful. 

I had a loop procedure two years ago for my abnormal cells which they say worked but only 6 months ago at my smear I was told that they were back to severe. I then had a colposcopy biopsy where they must of biopsied the wrong area because it came back as cin1. 6 months later I went back again and had an amazing lady take my biopsies this time and she told me that the person who did that failed me and I had severe. She said the previous lady was also meant to get my results looked at by a wider team but didn’t.
 my results for the recent one have just come back and they say they’re severe with possibility of invasive carcinoma. I feel so let down. 

should I be worried? 

has anyone been able to get rid of their HPV? Mine has been with me for a decade and I’m a healthy person who doesn’t smoke and sleeps well etc and pretty healthy!  

im 33

Thankyou in advance if anyone replies
