I know how you feel. I have had to leave so much furniture behind, by donating or giving away and it is sad. Now I have very little furniture and miss the ones I did have being that they aren't produced the same way anymore (or are too expensive for me to buy).
If you do need to part with a nice piece of furniture or can't do the restoration yourself, consider giving away on a site like craigslist or freecycle. Some cities are more active than others but better than throwing in the trash, and most will come to pick up so you don't have to lug to donation center or dump.

I was gifted an antique coffee table by a close family friend and was able to do some of the restoration myself. I am grateful for this and that I did not have to spend money on furniture made from wood from the US, exported to be manufactured in a another country just to be packaged and shipped back to US for resale.
