Guilt

I just found out I'm pregnant about two weeks ago. I had no idea, my husband and I were not trying to conceive, and I currently have a 10 month old baby girl. When I was pregnant with our daughter, I knew instantly. I felt so connected to her and was so happy. This pregnancy was not planned, we are dealing with a move, my husband and I are going through some issues, and I just feel so disconnected to this pregnancy. I am very sick and exhausted, so I feel guilty because of how that effects my time with our daughter. I don't have energy to do anything- I'm just not my best self right now. And I feel guilt about not feeling connected to this new baby. We had to cancel our vacation to Cancun next week for a wedding I was supposed to stand up in. I also just finished nursing our daughter and was selfishly looking forward to getting some semblance of myself back. I just feel selfish and guilty, and despite trying I just don't know what to do. Furthermore, I feel like a failure of a wife. I'm headed to bed as soon as the baby goes down and my husband gets home from work, I'm not cooking dinners, cleaning is minimal to just keep our place from turning into a dump- I am just so overwhelmed. I just want to be happy and excited.
