To me it also sounds like you are feeling quite lonely and left out of interactions with your children. Try to think outside of the box and think of some new things that you can do with your children, that are just you and them. For example, what are their hobbies? Do they like sports? Could you start going for walks with them in the evening? Just hanging out? Board games? Or you could take them to see a movie in the theatre or take them out to a restaurant just you and them? You could try making meals together with them, teaching them how to cook? Something that will help you connect with them and get that bonding time.

To me it sounds like being in the house is dragging you down, making you feel not as ease. Maybe you can shake it up a bit.
