Am i on my way to becoming anorexic?

i have been really upset the last couple weeks and stressed out since me and my boy friend just broke up so i havent been eating much if at all. I weigh my self every morning when i wake up and a few times during the day. I constantly lift up my shirt when ever i walk past a mirror and am usually not very happy with what i see. I am 5' 4" and weigh 139 right now which is probably over weight. I just want to look good in hopes that i can find a guy that will make me happy again...
