I broke up with my boyfriend and although I'm happy it's over it's the first time I've been alone since I was a teenager as I've always been in relationships. Now I feel constantly empty and sad and pretty worthless. It's made me realise that I don't have much of a sense at all of who I am and it's painful. I've been chatting to guys here and there since and I feel a boost of happiness once I have their attention but if I'm left alone I feel empty. I am really struggling. I'm not sure what to do, can anyone advise me? Maybe someone understands this feeling?
