I totally sympathize with your dilemma. I have the same problem in my 1960 ranch, and it was the one disappointment I could do nothing about! (I had always had the opposite problem!) So I researched how to decorate with low ceilings. There are several websites that discuss the options. Here's the benefit of my experience:

Hanging draperies at the ceiling actually makes the ceiling look lower. In most houses with normal height ceilings, there is visible wall above the curtain rod. So I've kept at least 1-2" visible above draperies.

Crown moldings are not recommended with low ceilings. My house has them, and rather than remove nad create another reno issue, I painted them the same color as the walls.

I also painted the ceilings one or two shades lighter of the same color as the walls. It gives a continuity and blurs the line where wall ends and ceiling begins. Where the color is very light, they're the same color. This is not m preference, but it does work. A white ceiling actually accentuates the low ceiling next to any wall color.

Keep furniture low. Avoid tall armoirs and cabinets. Hang artwork lower as well (although don't get absurd about that). Make rugs and furniture pull the eye down by making them the focus.

Avoid ceiling lights and fans, and choose "ceiling huggers" if you must have them. A chandy over the dining room table or pendants over kitchen counters or bedside tables will work, but middle-of-the-room ceiling fixtures don't.

Good luck.
