Simulation Exam help

Alright folks, back here for help again. I don't know what to do. I am in a non-traditional program so it complicates things. I am doing very well in the didactic portion of nursing school, but struggling very much with the clinical labs. We do not get a lot of lab time as compared to other schools and many of the skills have to be practiced at home independently. We do get a very good hospital clinical experience, but the labs are seriously lacking. Anyhow, I have failed 2 simulation exams now. This has set me back on graduation considerably and I now cannot fail another simulation exam or I am out the program. My primary problem is anxiety during the simulation exams. They are timed and it's causing me massive anxiety during the test. I do not get nervous around actual patients and do fine in the hospital setting, but the timing factor is making me a huge mess. I have already talked to my doctor about the underlying anxiety and have meds that I have just started taking for anxiety (probably shouldn't post that public, but oh well it is what it is and I'm tired of anxiety holding me back in life). Anyhow, what I need help with is figuring out how to tackle these simulation exams. I am trying to figure out how to practice and prepare for them better at home (and use my lab time most efficiently). I seem to not be able to think once anything deviates from what I think is going to happen. Once I'm calm and away from the scenario I usually can think the whole thing through clearly. I would seriously hire a private nursing tutor to help me, but it looks like all the resources out there are for people who have trouble with writing, math, or answering NCLEX questions. I do well in all of those areas. I just can't seem to apply what I know during the simulation exams. It's not even not knowing how to do the skills that is the problem really either. It's just staying calm and mistakes like calling the doctor without having all my facts together first. I'm making a lot of organization type mistakes. I think practicing lots of different random scenarios would help, but I don't know how to find them or where to look for help like this.

I am so very frustrated. I really think I will make a good nurse and honestly just getting tired of the nursing instructor weeding students out attitude versus really truly wanting to see their students succeed. It is wearing on me. I am discouraged. (I wanted to add that I was in a traditional nursing program 10 years ago, but did not complete it due to life issues - my kids were younger and it just wasn't working. I did not run into any of these problems during clinical labs and was at the top of my class then. So this is just very, very frustrating for me going from being at the top of my class to on the verge of being flunked out.) Any tips or ideas or even just encouragement would be really appreciated. If anyone knows any private tutors I'd be game for that as well.
