Unexpected pregnancy

Just found out that im pregnant with my 2nd baby. Normal ba makaramdam ng lungkot? 8 mos pa lang 1st baby ko :( Im a working mom. Sobra frustrated ako maging hands on mom kay 1st baby kahit na nagwowork Normal ba malungkot , yung feeling na takot ka na hndi mo mabibigay ng buo na oras at sarili mo kay 1st baby? :( Psensya na, 1st time to post. Gusto ko lang malaman if normal itong nararamdaman ko, dont get me wrong mga mommy Happy ako kay 2nd baby. Promise. Hoping sa advice nyo, and how to overcome yung gantong pakiramdam. Thank you in advanced mga mommy.
