Good luck to you.
If you have the time, since you've already got one degree, I would try for the Bachelor's degree, as that's the degree that in the long term, years from now, you might find yourself wanting.
Going ADN first is a good option as well because that gets you in the door and there are a wide variety of job opportunities as well. There are many ADN to BSN programs where you can get your BSN later.
I would talk to some admissions counselers, find out the requirements and waiting lists, and then start to decide. You might find the BSN requirements much more stringent, or the ADN waiting list much longer, so gathering more information by talking to the schools directly would be a start.
It can be confusing.
I'm moving your thread to the ADN/BSN forum, since you are asking a specific question and not just an itnroduction.
Good luck in all you do and welcome. Please feel free to ask any questions that you may have. We're here to help.
