I wondered for years where my mother had gotten that word. "You look like a glom," she would say, especially if I was unkempt, underdressed, and self-pitying. I'm not criticising her, it probably helped. I was never able to get a handle on what it meant, but the sound of it alone seems to convey it, doesn't it?
For random reasons I decided to try again, with similar lack of success. But DuckDuckGo gave me a link to Althouse in 2010, where she quoted the word "glomming" for males looking on while one man spoke with a woman. One of the commenters had apparently said
"Glom" was used by my mother to describe a sullen, unsocialised male: "you look like a glom in that shirt." Everyone else used it to describe attaching oneself or sticking on to something - glomming on to. Given my heritage, I concluded that the meanings were related to the Swedish word for oatmeal. I have been unable to find any authority who thinks this even remotely possible. However, a similar word roughly equivalent to "gloomy" was reported to me by a Norwegian.
If I had to push my guess beyond provable limits, I would relate it to PIE *ghel, melancholy, rather than Proto-Germ. *klamm, stuck together (clamp, clam).
I was thrilled to see this. It validated so much of my childhood experience. Except when I clicked through I found it it was written by me, in 2010.
