I would first and foremost commit to writing down every penny I spent, and sticking within a pretty stringent budget. Without details, it's hard to know what to cute. Clearly you need to "find" that $1000 and recapture 95% of it. But I but you can also cut your cable, cut your groceries, cancel Netflix, and more. These need only be temporary cuts, so let the carrot at the end of the stick be that once your can and CC debt is paid off, you can take back 25% of the cuts you made.
I assume you mean that your CC is at 0% until May 2019.
As for the car, frankly, you can't afford weekend trips in the PNW (or anywhere). You are broke. Broke people don't gt to go on vacation until the un-broke themselves. You say you are motivated to change. Well, this is something you need to change then. Time to put your money where your mouth is.
As for the car, you say you will "need" one when you move. Is that an actual "need" or an "it will be tough without it"? If it's an actual need, my first thought would be to not move in with your GF, or to move in with her only if you find a place that allows you to be carless. If you are moving further away, that is also going to increase your gas and operating costs.
