Feeling hopeless

I'm 29 and still not married and don't have any children. All I ever wanted was to be a mommy and a wife, but here I am with neither. I kinda of think I'm suffering from depression. I was diagnosed with PCOS years ago( of course I would be) and I know that depression can be apart of having this but amongst that I've been trying to conceive since I began having sex,with no luck of course....i ended up losing my left tube and ovary this past March and just ended my 12 year relationship with the guy who Never asked me to marry him or was Never completely invested in being a parent like me...here i am today saddened by my on misery and feeling hopeless....i just wanna crawl into a corner and wither away...i can't take this life of mine.
