Ugh

Well I attempted my first day of school and left halfway through class. I'm tired and th mere thought of school makes me sick at my stomach let alone being there I felt like I was going to through up. I'm not hungry and I can't understand anything. Everyone says it's normal but I'm becoming to dread 10 months of this. My host family is great but I just can't handle school. I want to go home but then I'll be that girl who couldn't take being abroad. I feel like this exchange is become pointless. What am I doing but distance myself from my loved once and stressing myself out so much I get sick. Is it really worth that?
