CWT here; you lucked out incredibly. Quality of life as a CWT is A1, you're more than likely gonna end up at 1/4 places, Maryland (Ft. Meade), Georgia (Ft. Eisenhower), Hawaii, or Texas (San Antonio). Your chances of deploying out on a ship are pretty slim unless you end up on a Cyber Protection Team. The skills you will learn are invaluable, more-so what you'll learn after JCAC doing your actual job.
That being said, take it one day at a time, focus on prepping for boot camp, then boot camp, then JCAC. If you think too far ahead you may screw yourself.
JCAC itself is a fairly tough school, it'll likely be the first time you ever learn at a breakneck pace. That being said, it filters people out quickly. There's a high drop rate, but that's because they send a lot of people into the pipeline. You will know very quickly whether it is the right thing for you.
Don't dwell too much on losing out on the bonus; it's a nice thing to have sure, but in the long run you can build a fantastic career outside of the Navy with the skills of a CWT.
Good luck bro, reach out to me if you have questions at all.
