Dreaming_310

Hello, I know this question can really only be answered by me, however I am looking for some feedback. I am a 25 Year old male and since I was about 10, I have dreamt of pursuing a career in Healthcare. I love everything about it. I love science, continuously learning, pushing myself to succeed, helping people and giving back to society. I had a tough time growing up and had to drop out of high school so I could go to work and support myself. I have lived on my own since 16 and have supported myself and have managed to save a little in the process. Though I have been working in an area completely unrelated to Healthcare/Medicine, I have always done my own research and learning during free time. I am now done with my past and want to move forward. I applied to college this year and was accepted. I start in January. Since I did not complete high school, I had to apply to a Pre-Health course. This gives me an intro to college level Bio, Chem, English and Math. Its a one year course and it gives me the time to think about what field I want to branch off to. My ultimate dream was to one day become a Doctor. I love Medicine and everything to do with it. I love the diagnoses, the complexity, the challenge and of course the reward. I just feel that Medical School at this point is only a dream. I do not have a college fund nor do I have the family support. I'm not sure however if student loans cover the costs of becoming a Doctor. I do know that I have the means of getting my Bachelor degree in Nursing. I have the passion for it and know that I can succeed and live a happy life as an RN. My problem is, will I be disappointed? Will I always be watching Doctors and thinking about how I haven't lived up to my dream? Or is Nursing as rewarding and challenging that I wont even be thinking like that? I know that practicing medicine and nursing are totally different, but after all, we are all working in Healthcare, with patients who need our help. My last question, over the years I have done a considerable amount of research in Biology, Organic Chem, Disease and Treatments. Will I be bored with Nursing because of the knowledge I have obtained throughout the years? Or will I still be challenged? Thanks for reading this, I hope someone out there can give me some feedback. I'm almost positive that others' have been in these shoes, and I would love to read your stories. Thanks a lot!
