Will I ever meet someone who I can love again?

The pathetic thing is that 2 years ago I fell in love w/ a guy who broke my heart. Initially, I really tried to date people, but every time things just never worked out. It's been hard for me to meet people. My work schedule is really chaotic and I can work over 18 hours every day including weekends. I suppose that this is no excuse. I think that I've just given up. Do you think that it's worth actively looking for someone or do you think that you can just sit back and wait for the right one to come by?
