Totally confused!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hi I am fairly new here, but I am in dire need of some advice/guidence. here's my story............................

I recently decided to go back to school after 15years (I will be 33 tommorrow) out and in persue of nursing. Doing my pre-reqs and was very excited about going back to school. Still am but now I'm just totally confused. See I never went to college after high school and have bounced from job to job not liking what I am doing with my life. Since high school I have always had an interest in the medical profession. The 2 careers that I always bounced around in my head were nursing or xray tech. I know 2 totally different fields. But I went with nursing because something was just tugging at me to do that. But recently I have found a program at a hospital about 40 minutes away that does xray. One the one hand I want to do nursing because I want to be challenged at all times which I think nursing can give me that, and I want it to be rewarding to make a difference in someone's life. The money thing is just an added bonus. Not really persueing a career for the money. But after reading some of the posts on here I am scared to death that if I do become a nurse I will make a huge mistake and end up killing someone! The area of nursing that I want to consider is OR, women's health, NICU. But that could change once I do my clilnicals. I just have a feeling that I wont be a good nurse and scared that everything is on the nurses shoulders.

On the other hand, x-ray has always interested me too. But it may not be as challenging as nursing. I get bored very easily which is why I need something challenging. the x-ray school doesnt require so much pre-reqs so it may be easier to get into. Not sure on that. It is also full time days. The nursing program I will be going to is part time nights. So I can still work at where I am. If I did the xray I would have to find new job at nights which would suck because of family obligations (2kids,etc). I just dont knoow what to do. I'm just having a fear that nursing would be over my head. That I wouldnt be able to handle it all. I mean I love the fast pace of it all just afraid i would forget something and end up hurting a patient. Not something I want to do. Has anyone out there has had a fear of this? Or a dilemna of their chosen career path??? I know I can only decide for myself but if anyone was in a similar situation and can share your thoughts it would be greatly appreciated!
