Is it normal to have given up on life and love?

And to think life has no meaning and to have lost all your interest and happiness. I do not have depression, just have failed and been hurt and rejected so much I am cynical. I am not suicidal, just think like really has no happiness. I used to think it did, now I am older (30) I feel I have nothing. No job, no car, a house I rent, no partner, kids, a family who forgot my birthday, no friends. I have tried many things, working, volunteering, study, but find after a while my happiness goes. WHat could be wrong with me? I thought I met a good boyfriend but found he was cheating on me.
