It sounds to me like your depressed. I went through two years of being 'clinicly depressed', my most memrobal symptom was crying for no reason, i would burst into tears if the traffic lights turned red! Also I could go 2 days without food and then binge, I convinced myself that none of my freinds really liked me, that they were just pretending to. The worst for me was the not sleeping, I remember still being awake when the sun came up and so of course bursting into tears. I don't know if you have any of the other things that I had but I would say it's worth speaking to a doctor. It's good you have the support of your bf, ask him to go with you, I took my mum with me and i was 24! Good luck and feel free to contact me if you want a chat.
