Another bad day :(

I am just not having a good  time lately.  I keep getting sick, everyday.  Making lunch for my sisters makes me sick,  I can't stand food.  Yet, I suddenly thought the other day..ooooh I want a cookie.  I think I'm going nuts.  Plus, my boyfriend may have had unpleasant  motives.   I think that he may have just been using me.  Why else would he wait to ask me out until right before he knew that he had to leave for boot camp.  I feel like such a fool.   I should have used my better judgment and not had sex with him.   Then I wouldn't be in such a bad place.  I feel so stupid.. I don't know what to do anymore.   I just wonder.. when did I loose all of my common sense??  And will I ever get it back??   I thought I was smarter than this, I thought I could say no when it wasn't right.  I was so wrong.  I should have said no.  I knew it was wrong, I knew it was not going to end well.  Yet, I still just gave in and let it happen.    I guess I thought that if I just did what he wanted he would stay with me.  Now I have no idea what is going on.  He might have just wanted sex, and I gave it to him.  What if I never see him again??   I sure hope that I am not pregnant, that would really suck.  I really don't know what I am going to do.
