Leep procedure

so about a year ago i was diagnosed with precancerous cells on my cervix due to HPV. they are considedered high grade and potentially dangerous.

I have to get the Leep procedure soon and I was just wondering if anyone knows anything about it from experience. im worried that I have low pain tolerence and i have high blood pressure so I might bleed A lot. ive done my research and i know what the surgery consists of. but im just really scared and worried.
