Feeling guilty having a second baby?

My daughter is one and after this year I have really thought about not having more kids because she's honestly a lot to handle & she's perfect. I'm on BC and BAM I just found out that I'm pregnant. I'm struggling because I am so damn scared on how I am going to keep up with two kids 😭 also I feel so damn guilty my daughter isn't going to get the attention she is used to. I breaks my heart :(
