2 yrs no luck

Two years of TTC. I don't know what to do. It is literally consuming me and I constantly feel depressed. I've tried everything affordable to us right now and I've had a couple of blood tests (normal) and she told me it just takes time for some people. Well Idk what to do because they say the longer it's been the less likely it is to happen on its own. I am devasted. :(
