anyone feel suicidal over inadequacy?

I simply can't handle another BFN. I do not live my life just to have kids, but I'll be honest - constantly realizing you can't get pregnant when bottom feeders and trailer dwellers can't handle all the kids they have is quite a hit to the innermost parts of a person. 
This is really going to put me in a severe state very quickly.  Trying to relax and let it happen is weird to me... Having sex willy nilly doesnt increase chances!
