So overwhelmed!

Hi everyone. This is my first post and I'm only posting because I'm feeling extremely overwhelmed and anxious right now. I feel like I've been experiencing an ongoing panic attack for the past 3 hours. I'm 19 and 3 months pregnant with my first child. I just reached the 12 wk mark yesterday. Maybe I'm so nervous because I'm in my 2nd trimester already? I feel like I just took the pregnancy test! Is anyone else feeling this way? I just need some uplifting words and support.
