Honestly dude, you really need to get used to making readable code. I used to write code like you did, and honestly it really backfires in the future.
When I went on to make my AIO thieving script, I used the same method I did for every other script. This left me with 1000 or so lines of code in the onLoop alone (and this was before the script hit beta). It took me much longer to debug than it should.
When I moved that script to a more readable framework, everything was so much better. Even though I have more classes, I can debug quickly and I even got rid of a lot of code by doing so!
And don't be discouraged when your scripts get a lot of files, it only means progress For reference, here is what my AIO thieving script looks like (file wise):
I use 3 classes just to have a list of all the banks in RuneScape. I have classes which literally just reference methods in another file, too. But believe me when I say that this has helped.
Good luck, and maybe one day you'll be releasing scripts on the SDN!
