Why is life so confusing and hard!?

[Lucy]

Okay so when I was younger around 13/14 years old I was really comfortable with people around me, I had a really close knit group of friends and many guys wanted to date me
but like I feel after going through 2 horrible break ups I have just lost confidence in myself and people in general..
i'm 18 years old now (in university) and haven't had a boyfriend in 3 years!! I don't think there is anything wrong with me.. many guys have added me on Facebook after seeing me around uni and once we get to talk the conversation just fizzles out..
it's so annoying, whenever I go out to clubs, there's always a guy trying to buy me drinks, dance with me but I just want a guy to really like me for who I am..
Many guys have said that they think i'm hot but I think I don't have great confidence it may be because i've been bulimic for about 4 years of my life..
so lost and confused, i really wanted a good start to university! i've made a couple of really cool friends but sometimes when I'm out with them, I just go into this depressed mood and I don't even know why..
