I suck why?

Why i suck cause am still holding on to the past and i can't freaking let it go. Whats even more worse is i keep having a dream that i confess and thingss went better again which we all know is bull. Ugh, i dont know why this is lasting so long? am afraid this will go on to long. It feels like am better off single not knowing that i can't love someone. argh! i really want to stuff my self in a closet.
