15 weeks and feeling so rough.. feel like I’ve been hit by a bus. Where is this 2nd trimester honeymoon feeling this app keeps telling me will happen now?!

I’ve had migraines, my whole body aches, I’m exhausted, I have 0 energy or motivation I feel sick still.. anyone else? I’m absolutely miserable now and so over it. I want my energy back I want to feel human again. I’m so happy to be pregnant but it’s so hard to get out of this low mood when I feel so crappy.
