Yes, it would be a very good idea to check in with your doctor & hopefully a specialist like a psychiatrist (ie someone who can order blood tests and prescribe medications *if* they are indicated). If you are in the Northern Hemisphere, did you notice the onset coinciding with the shortening of daylight? If you are in the USA, did it coincide with the chaos surrounding the elections? It would probably help the doctor(s) if you can figure out when it started and whether anything else was going on at the time.
I didn't learn to weed apart ASD/AS/Sensory issues from likely bipolar until I was in my 40's. Even now I'm not always sure, but I figure if there's no outside event I can correlate with, it's probably "just" the cycling of my mood due to a family history of such. So, I hunker down when its the bad time & try to restrain myself when the opposite hits. If it ever reaches the point where I can't, I'll get drugs to help.
