Not looking back.....

when does this feeling come easy? just a quick little background on me, i am originally from texas *love my san antonio spurs*. my husband is in the military and we are now stationed in mississippi. i have been a personal injury paralegal for the past 7 years and honestly have been successful and made good money. however, my heart is not in it. i do not feel like i am doing any good for the world. i've always had that feeling that nursing is what i should have done. after i graduated high school i was planning on going to nursing school. however, i ended up going overseas and it didn't happen. i went to paralegal school instead. for the past year i have been going to school part time trying to take the pre-reqs and working a very stressful job that required long hours. this summer we were transferred to mississippi. it was a huge decision to sell my house and give up the security of my job and moving to ms. i'm 27 and at that point now where i know if i don't just do it (try to get into a rn program) i will continue to have that feeling of regret. however, i'm having this nagging feeling i guess maybe that i am being selfish by not working or bringing in an income. i'm also scared of failure. what if i do not get into a rn program? my husband is super supportive and is completely okay w/ me doing this. i am scheduled to start a cna program at the local community college as well as taking a&p ii and trying to register for a couple of more classes. this is a huge plunge for me as i know a lot of you have made. i guess i'm scared of giving up my career and attempting to start a second career. i'm trying to supplement a small portion of my income by becoming a cna, as well as more importantly get clinical experience. i'm just waiting for the feeling of no regrets...not looking back. when did you become completely comfortable with your decision to quit working and/or give up your career. thanks for reading all of this and any comments.
