I was fun too before my boyfriend. I think it's because you become tied down with worries about your relationship that you become stressed and paranoid. I'm always afraid that he's cheating on me because he's always flirting with other girls. I take out any of my problems on him and I half believe that if I wasn't with him I'd be more relaxed.
I was put on anti-depressants when I was 18 I took them till I was 21 then came off them... I'm just sick of being like this, I want to go back to the old me :\
I don't know. Boys mess you up.
