12 week scan 😢 please help me im so upset

Natty • Pregnant with my second child due January 12th

Why am i not happy to be going im not excited at all if i wasn't going it wouldn't bother me at all. this was a planed baby and was very much wanted but im dreading the whole thing this will be my 2nd and my now 5yr old is very challenging she has no metal heath problems or anything she just has a strong mind when she was a baby she never slept at all even been a newborn and to top it all off i had a hard time in labour had post natal depression to top that off so i think alot of it is im worried im going to have another baby that dont sleep and get post natal depression again!! I love my daughter very much but sometimes its hard.

Was your childen the same or was they completely different please help!?!!
