I'm so miserable 😞

So for the last week I have had terrible insomnia, I can not sleep and when I do it's not for long at all. I just lay awake staring at the ceiling. I've also been pretty moody and emotional, bad bad acne.. just miserable to say the least. I'm not happy with anything and I'm making my fiancé miserable as well, we are ttc and it hasn't been an easy journey. Idk if that is starting to cause stress or what. I'm not PMSing my period was just a week ago.. idk what's wrong. Anyone related to this?
