Disconnected

Hi fellow mummies, does anyone feel strangely disconnected with their husbands and friends? It is our first child. My husband has been wonderful, we have a good relationship. There’s nothing more I wished he would do. But I just don’t feel so connected and keen in physical intimacy. Meeting friends whom I love too. Idk why but I either don’t look forward as much or just feel more tired during and after the interactions. I wish I can be myself again.
