I\'m a dick head

I got drunk yesterday on a big night out. I started yelling at my boyfriend for "having an affair", Threw up, cut myself, then cried for a while.I'm really irritated with myself, I've acted like a prat and there was no need for me to self harm, I didn't even feel like doing it I just did it for the sake of it. I had gone 7 months without doing it, which I'm still really proud of but.....I just think I'm a prick right now!!!Plus I haven't eaten for three days after a spout of being sick. I'm tired of feeling ill, I'm tired of medication withdrawals screwing up my progress! GRRRR
