I'm not going to tell you what to do, but there are advantages and disadvantages to both routes. Whichever route you take, the total time in school will end up being about the same (provided you are diligent), so don't let anyone tell you otherwise.
Going the ADN route puts you into the workforce earning money faster, which is a definite advantage. The downside is that while you are working on your BSN, you will not only have to contend with your school responsibilities but work responsibilities as well. Some places you work might give you problems working your schedule around a school schedule, which tends to be pretty inflexible. Beyond that, I have met more than one ADN planning on being a CRNA who essentially got lazy after earning their ADN. They were working, out of school, and earning a living. They wanted to have a little fun, and found additional school work was just a drag. In fact, I was told by one this week that she had decided not to go any further right now, because "she just couldn't get back into the swing of school." I've read your previous posts, and I know you are pretty determined, so I don't really think you would have that problem.
ADN programs are great for teaching the clinical side of things, but have a little less in the hard science prerequisite requirements than most BSN programs. I know you have taken chem and (I think) physics in high school, so this wouldn't really be a problem either.
A BSN program takes longer, and involves prerequisites that don't really have much relation to your goals. However, you can take classes as electives (such as elementary physics and a level two chemistry course) that will help you when you get into a CRNA program. Also, most BSN programs will require a statistics class, and almost all, if not all, CRNA programs require a statistics class as a prerequisite for entry. But, a BSN program puts you in school for two more years without earning RN salary.
I went the BSN, work, CRNA school route, and it worked well for me. But remember, I am a disabled veteran, so my BSN was paid for, lock, stock and barrel by the US Government. This payment went so far as to pay for my nursing uniforms needed for clinicals, and equipment such as a stethoscope, etc. When I was done, I owed the government nothing, so I had fewer money worries than most college students.
My daughter, who is now 20, has decided she wants to be a CRNA. She is taking the ADN route, and I think its going to work well for her. (And yes, I am both very proud and very flattered.) We have worked together to map out a strategy for her, and I think she will do well.
Bottom line: I know you to be a motivated, dedicated student. Either path should work well for you. So, the decision rests with you. Examine the advantages and disadvantages of both paths, and decide which works best for you. Follow that path with determination, and you will do fine. Remember, whichever path you choose, you have a lot of hard work ahead of you. Your fellow students are probably not going to be as dedicated as you, and will look down on you for the hard work you are doing. Stick with your plan. You may not be able to party hearty in college, but just remember how much more partying you will be able to do a few years down the line, when you are earning 120 - 150 K and your college classmates are earning 30 - 50 K as staff nurses. The extra 100 K equals much better, much higher quality party time. Stick with it.
