IUD making me moody? what?

I had my IUD put in February 25th. These last few weeks I haven’t been myself I feel… I’m always moody & argumentative with my partner.

Yesterday while he was holding me in the kitchen he tells me how I’m always mad at him. He wasn’t mad at me, he was more so just telling me. I wish I could fix up this attitude of mine. Idk what’s going on with me, I just wish I wasn’t being like this towards him 🙁 he’s so loving towards me, I want to be like him towards him. He’s so affectionate & loving, I don’t deserve him.

I can’t even sleep in the same bed as him, I toss and turn forever. My legs are so restless. I sleep downstairs with our son who is almost 1 & I probably don’t fall asleep until 2am almost every night & I’m up at 7:30/8.

I’m also dealing with college, it’s exam week this week & I’ve been stressing about my grades & all that. 🙃
