I'm Pregnant with my second and scared.

Basically the title says it all. I just found out about 45 minutes ago. I've been walking around like a zombie my mom trying to tell me it'll be ok. She had 3 foot step kids and made it. My oldest will be 6 in March. So any of your 2nd + moms could you give me advice. Will I love my 2nd as much as I love my son. Is it harder to take care of 2. I'm 27 not married but do have a wonderful bf.
