As others have mentioned, Asperger's and autism are now the same thing, so you would be perfectly justified in calling yourself autistic. Personally, I'm getting re-evaluated at the end of the month because I feel like ASD level one is no longer appropriate for me, since I too feel that my autism is worsening. At the time of my diagnosis, I was going to university full-time while simultaneously working in a loud, bright environment, I attended after-school clubs and hung out with friends.
These days, even leaving the house can be a challenge because everything seems so much louder and brighter than it ever did before. I cannot work well due to my terrible executive functioning, and have job coaches that are helping me look for simple work I can manage that's well below my education and intelligence level. I prefer writing to speaking these days as well, and find it easier to write my thoughts down rather than communicate them verbally. My meltdowns have also been progressively worsening. I had one last week because I was frustrated that I couldn't find the words I wanted to explain a problem to somebody.
It is very possible for autism to get worse, whether this is through organic causes or increased environmental stress, I don't know. I'm under far less stress these days than I was five years ago when I received my diagnosis. I'm not going to work or school, I'm financially secure and don't have to stretch to pay my bills, and I have no real responsibilities beyond getting myself to my therapy appointments, which I attend of my own volition anyway. I have absolutely no idea why my autism has gotten so much worse.
