I am a horrible pregnant person

I had always pictured coming into motherhood through adoption, even before I got together with my now husband. Over the years he wore me down into thinking carrying my own child would be a better plan for us. 
I'm four months pregnant now and I am struggling so much. The first trimester was really hard sick everyday, multiple times a day. The migraines were the worst :( I felt so bad and had zero motivation to do anything. despite being in an exciting time in my life my depression made it hard to get out of bed. Now I'm struggling with irritability and hormones. I'm happy to be pregnant but I just don't like person I am right now. 
I hope this isn't a sign of my motherhood experience to come because this sweet baby doesn't need a rage bitch for a mom.
Ps. Please send good vibes to my husband because I have no idea how he puts up with me.
