In a dark place

I font know where to begin or what to even say. The past week I have been in such a bad place. Things I used to care about I have no interest in, people who mean the most to me I barely talk to and when I do it’s just short responses. I have no interest in talking to anyone or even leaving the house. I blame part of it on our fertility struggles. We’ve been trying for 2 1/2 years and are on our third cycle of iui with donor sperm. But I don’t think that’s what is causing all of the way I’m feeling. I’m lost. I don’t know what to do.
