The paranoia is back

OmG....why do I worry so much? I just made an appointment at a ultrasound center for when I'm 9 weeks, so my boyfriend and son can see the baby and hear the heartbeat...its next sunday.....hopefully everything will go well.....I will be 8 wks tommorow and some of my symptoms have calmed down a little bit....is this normal....the fatigue has went from feeling like fighting sleeping meds to not wanting to do anything and my boobs are still sore but not like they were a couple of days ago...is anyone else going thru this....
