Keep your head up! I know how you feel. I'm not sure how old you are, but I am 36. I wanted to be a nurse since I was 4. I had it all planned out in middle school of what college I would be going to and what hospital I was going to work at. Well of course things happened(my father died, and my mother remarried, moved us, and then divorced) I chose a diferent college, and began, but only went 3.5 semesters. Due to my families financial issues I was working full time, trying to go to school, and ran out of money(had high debt). So I dropped out of college. At the time the nursing program
was very competitive, like it is now. So that made it very frustrating as well.
My life desires became more focused on settling down and having a family. I came close several times to go back to school, but financially felt it was impossible... and felt I just wasn't going to be smart enough to get through.
After having kids and being a stay at home mom, I felt even less smart from being home w/ kids all day. I felt like the desire to being a nurse would never happen.
Well, when both of my kids started school, and I decided to quit feeling sorry for myself. I thought I would give college a try. I couldn't afford anything but the community college, and was nervous to go back to college in my 30s, but I want to be a nurse so badly. I have had to retake practically all my prereqs, and only went part time. So its been 2 yrs, and now I am waiting for my acceptance letters( I got into the LPN, but hoping I got into the RN too). I can say I am muched more focused now, and am shocked I have earned a 4.0.
I think if you want it bad enough, you will find a way to get it. It is a long road, and a lot of work, but isn't everything you do in life?
Hang in there, I think it is worth it, and if you struggle on some of the science or other classes, ask for help. I have found the professors to be amazing and understanding, if you just talk to them and ask.
It is very overwhelming for as long as it takes and how competitive it is, but for me it is allowing me to fulfill my dream, to be proud of myself, and show my kids that anything is possible at any age. ( I just wish my dad was here to witness it, as well as my uncle and grandma whom just past this year).
Stay strong and hang in there. The semesters do fly by.
Sorry for such a lengthy response, but I hoped it helped alittle.
