I'm having anxiety someone please help!

Okay, so I just recently had my first child on January 17 2017 (this past year). I found out that I am expecting again on September 21st. With my son, I had to have a c section because of hypertension and I was not dilating even after being induced. I mean 18 hours and I seriously didn't dilate at all! I decided that I would like to try to have him naturally so absolutely nothing for pain. I went without until the dr said it would be best to go ahead and do a c section. Anyways, I was all up for it because I was over the back pain and the contractions! So they took me to the room for the procedure and that's when they had to give me an epidural. Well, the hospital I was at was a teaching hospital so a student was the one to insert the epidural into my spine. Well, he didn't do it correctly. It took him 4 tries before the anesthesiologist decided to take over to do it. It wasn't the needle to me that hurt, it was feeling the fluid or whatever it was hit my nerve or bone that bothered me so much. It's so hard to explain and I don't enjoy talking about it. When they finally got it right the dr explained to my husband that they went to deep and then they didn't go deep enough and that's what was going on. I was numb all the way up to my neck. Now that I'm pregnant again, I can't help but think about how awful that was. I have severe anxiety just thinking about it and I'm so terrified of getting another epidural again. I need advice on how to go about my anxiety and how to keep from freaking out when it comes time to go through it again. Help!
