I recommend reigniting your passion for writing. You could approach it by focusing on why you love writing and what originally got you into it, and draw inspiration from that. Alternatively, you could try listening to music more, or read someone else's story, watch a movie, take a walk in nature, or do anything that inspires you and gets your creativity flowing. 

If none of that works, maybe you just need a break for a bit. No point in forcing yourself to write if the ideas just aren't coming, that would likely just stress you out. Maybe if you took a week or two to just relax and not focus on writing at all you might be more refreshed to start coming up with ideas again.

So it sounds to me like you're having trouble separating the characters viewpoint in the main plot as you are trying to keep the main plot in mind.

That does sound about right, actually... I mean when the autism is given more focus for a plot, it's not as hard to make it work. However, if I say... put an autistic character in a situation where they are being bullied and someone sweeps them off their feet by protecting them, it becomes harder for me to bring out their autistic traits.
