I must have a surgical abortion and I am terrified. I will be awake, anyone with experience willing share?

First let me say this is not something I want. I have had numerous female health issues and recently found out I have ovarian cancer. I am having an abortion with the advice from 2 different doctors. They have ured me it is literally a life or death situation. If I abort this baby, I might live to become a cancer survivor and could eventually conceive and carry a baby to term in a few years. But for now, I must have an abortion. I am about 5 weeks, but will be 6 weeks by the time I have the abortion. I am so scared. I have to stay awake because of other medications I am on now, so even twilight sleep is out of the question. They told me I would get a shot in my uterus to numb it. Does this shot hurt? It seems like it would be extremely painful. Then they will suction me. Does that hurt? They told me the procedure would last roughly 10 minutes. I am so scared, I don't know what to think. I am horrified at the thought of having to be awake during this. If anyone has any experience they would like to share with me, I would greatly appreciate it. For those of you who are just going to put me down about this, don't waste your time. I already feel bad enough. I have been crying for the past 5 days, since I found out. I am begging God for forgiveness and plan to start counseling next week as well. Thank you for any and all help you may be able to provide me.
