I'm having Y-90 procedure: What can I expect step-by-step?

I'm absolutely petrified about this procedure. What do they do step by step? I'm afraid of the needle going into my groin. Will I be awake when they do this or will they give me pain iv medication before they do it.? While they are doing the procedure am I awake and feeling everything or Am I asleep? I'm so afraid that I almost want to cancel it. Ie been through so much and I'm having to have another surgery with in 4 weeks to have my ovaries removed and I'm just so afraid of everything lately and I'm just so tired of being sick and tired all the time. I'm terminal so there is no cure for me so I feel like I'm doing all these procedures for no reason because it's not going to save my life. I don't know if I'm making the right choices. Should I do these treatments or just live what life I have left without having to go through all the pain from these surgeries and procedures. I also live 2 hours away so it's an all day thing everytime I go. I guess I'm just frustrated because I'm only 54. I got breast cancer from the environment. No one in my family has ever had cancer and I'm not even a gene carrier. It just all seems so unfair. I've taken such good care of my self my entire life. I've never smoked or done drugs and here I am fighting for my life at 54. I'm sorry if I sound like I'm having a pity party but I'm just so afraid. I have no siblings, my mom died 2 months before I was diagnosed and I now take care of my daddy. He lives with me. I have 3 grown adult children but I don't want to be a burden on them. I do have a counselor but he's pretty much useless. I feel like he just says the same thing over and over again. I just feel so alone. And I'm scared shitless. I have a great husband but he doesn't like to really discuss all these things. I guess it's hard on him as well. But it just makes me feel so alone sometimes. Well if anyone reads this I could use some prayers because I'm really afraid.
