A bit of historical context on autism terminology, re: the switch from autism, aspergers, and PDD-NOS. Before Aspergers was recognized as a diagnosis, the first autism diagnosis was given to Donald Triplett. Donald, who is still alive, would today probably be considered very "high functioning." I'm not personally a big fan of functioning labels, but since it's common terminology I'm going to use it here. Donald graduated college, lives on his own, drives, and engages in social activities regularly. Basically, the autism case that set the precedent for the autism diagnosis doesn't really look like what we currently characterize as "classic" autism. Hopefully that makes the terminology change make a little more sense. Autism is a spectrum and people who may seem "high functioning" in some ways may seem very "low functioning" in others, and vice versa. Trying to draw lines between autism and aspergers (and PDD-NOS) is really difficult and really isn't as helpful as it seems at first glance. If people choose to self-identify as having aspergers of PDD-NOS that's understandable, but I do genuinely think that from a diagnostic perspective autism spectrum disorder is a more helpful term.
Anyways, it's possible that you had autistic symptoms as a child but were never diagnosed. Some people don't realize they have autism symptoms until they are older because they are suddenly forced into more social situations, and forced to deal with more responsibilities in caring for themselves.
Also, check out autism burnout, it can help explain why autism suddenly seems to get worse.
It's also possible that you aren't autistic, but have sensory processing disorder.
In any case, sunglasses can help with light, and I know some people prefer incandescent light or natural light to fluorescent lights (this isn't the case for me, natural light is extremely painful for me, but it works for some people).
Also, look for sensory experiences that help ground you, such as soothing textures or sounds.
