Is it normal to be really scared of my hpv jab

Ok I'm Going to have a late HPV jab soon and I'm REALLY scared. There is three rounds of injection on diffrent months. When I was young I had to have a drip put in my hand and I jerked and they cut alot of my hand. Ever since I have been really scared and missed a jab when I was 10. I have heard by other girls it REALLY hurts but then I think they exaggrate. I have been a nervous reck for a week and it has made me ill. I want to have the jab but I think I will cry or faint when I have it done. When thinking about it I shake. Can anyone tell me what it's like truthfully, and what helps????
