Giving up...

So after almost a year with no changes I think I'm giving up... If I had normal cycle or something I would keep my hopes up but depo severely screwed me up so I guess it's up to "fate" now. After last month I got my hopes up because I had my first "period" in forever, and first since stopping birth control all together in January. But I guess that doesn't mean they are going to keep coming. Haven't had one yet and thought I could be pregnant but looks like I'm not.... Im ready to cry because everyone else around me is and I feel like I'm doing something wrong. I don't understand why I can't just do 1 basic thing women are created to do.
