I'm impressed by what you've written so far and by your obvious commitment to having a GSD. There are some things that, in addition to the good suggestions above, I'd suggest you consider as you reach a decision:
1. Have you considered what type of GSD you'd like (e.g., show vs. working line) and what you'd like to do with it? There are exceptions, of course, but, generally speaking
, those lines have different drives/needs that will require more/less effort (i.e., training) on your part.
2. Speaking of which, what kinds of things would you like to do with your dog? Different activities will require more concentrated and consistent effort on your part than will others.
3. Have you considered an adolescent (6+ months) or adult (2+ years) dog? Each age can bond tightly with the family, but their needs will differ considerably, with different time demands. I saw that you preferred a puppy, because you'll have time for training in the coming year, but training can last well beyond that. Keep in mind that if you do get a puppy in the near future, it'll be entering the dreaded period known as adolescence just when your time may become more limited.
4. Consider putting together a detailed budget of expenses related to obtaining/keeping a dog. It's good that you have an emergency fund, but one unplanned surgery can wipe that out in a nanosecond. (Look into pet insurance --- lots of threads about the topic here --- as one way to defray emergency vet costs). Also, the cost of purchasing a puppy isn't the only 'upfront' expense you'll encounter; unless you have everything to hand already, there's equipment (e.g., collars, leashes, crate), well puppy visit, food, toys, etc., etc.
5. Consider waiting until you've concluded at least the first year of college before getting a dog. I see that you've been dual enrolled (again, impressive), but that's not quite the same as full time enrollment in a college program. The reality of scheduling, etc. may be different than what you anticipate it will be. You can use that time to investigate lines, find a good breeder, or breed rescue. .
Having said all that, I am sympathetic. I had a dog while in college and never once regretted it. (Well, the reality of living with an Airdale gave me pause, but that's a different issue
). It took a lot of time and effort. I did have a roomie, but it was my
dog and my
responsibility. All four years. Would I do it again? Not sure, it was a different time and place. But, I believe if you want something badly enough, research your options, plan carefully and then go for it.
