What's going on with my body? help please

Lately I have been way less hungry than usual, I normally eat a lot throughout the day now I've just been eating once a day, my lips have been getting SO dry at night to the point where they split open and that's definitely not normal for me and I have been crying a lot basically over anything and everything 😂 i cant think of what it could be. does anyone know what my problem may be? 😂
