Pretty common problem actually. Since you're allowed to use an analysis board in "online" (what everyone but Erik calls correspondence) chess; why not set up a real board next to the computer so you get used to going back and forth between 2D and 3D?
Chess on computer vs real life chess.
I ran into this just the other day. When I started playing chess a long time ago, there wasn't online chess; we only played with a "real" chess set. Then I took decades off and started playing here at chess.com a few weeks ago, all online. Yesterday, my son suggested we play a game, so I dusted off the old board, set up the pieces and... Whoa... It looked really weird - the pieces seemed in each other's way.
It took about five moves for the sensation to wear off and then was quickly forgotten, until your post :)

Good Morning James, As you know I started an elderly OTB chess club and have found going from Internet to the board depends some on the board as well. Actually, I found the Tournament board which seemed giagantic to me at first to be the clearest. We had a smaller magnetic board and it seemed more difficult, especially seeing diagonals. I think Mark R's comment expressed the norm for persons playing online and OTB. Good Luck!
I have been playing chess for about 3 months now and i have only really played on the computer. I tried to play on an actual board today but found it quite difficult to see moves ahead and tactics. Has anyone else had/have this problem?
