Don't beat yourself up! It's a very, very common thing to overwater indoor plants, especially over winter. I've done it myself because some plants really need a lot less than others.

Many people see them drooping and think they need more water but drooping can also be a sign of overwatering. If your plants haven't started growing brown and mushy, there's hope! Just leave them alone for a solid week or two to dry out and they might come back yet.

It's a good thing that you care for living things and want to keep them alive rather than neglect them, that's what makes a good plant parent :) and now you're learning!
