I have suffered from quite severe anxiety and depression over the past few years (I have EUPD) and one thing I can tell you for definite is that keeping your mind occupied is incredibly important. The hardest thing is going to be maintaining a balance between caring for your mental health and supporting yourself financially.
I'm not going to tell you not to worry or that "it gets better" or anything like that because it's disingenuous. It's most likely that what you're going through is your mind having an aversion to what it sees as the responsibilities of adulthood. The good news is that this can be overcome and even if it's something on a more fundamental level, with practice you can live a normal, functioning life.
If you suffer from high levels of stress, try not to seek constant distraction as it only pushes the can down the road. Take time everyday to apply to jobs, don't let it get you down if you aren't getting replies (there's plenty in the same boat). Try to make your bed every morning and have a shower, do laundry, cook food. Perhaps you could write yourself notes to push yourself into taking these steps. If you spend long enough pretending to be a normal person, you might find that you don't have to pretend anymore.
