HELP! Accelerated BSN OR Accelerated DE MSN

Hey Everyone... I am extremely interested in nursing. I have a BA in Psychology and joined a teaching program after college that is a 2 yr commitment. I am about to begin my 2nd and last teaching year and being in my program I realized I did not want to teach/be a school psychologist like I had intended.

I began volunteering @ the local hospital and fell in love with teaching. So I plan to go back to school the nontraditional route to accelerated programs in Boston.

UMASS offers an accelerated BSN in 15 months (I'm beginning my requirements now)

Boston College offers an accelerated direct entry MSN program where you graduate with an MSN NOT a BSN.... but I think you have to specify depending on your interests and as of now I really enjoy peds....

So Idk which one I should do I really do not know what to do.... before I heard of Boston College's program I thought I would be an RN for some yrs and then do a graduate program specifying on what I would like. Also if I like being a crna I cant do that with the BC degree because I would need a BSN degree which I would not have...

I would really appreciate any advice
