ttc with depression.

I've always had depression sometimes it hides but it never goes away. As you know TTC is hard for people who have fertility problems I'm not sure if I do but its been almost 2 years I haven't gone to a doctor I know I should but it might just be the end for me. Its 4am and all I'm thinking about is how a baby would bring me so much love and hope for the future but its starting to fade. I'm nothing I'm no one. What does my future hold?
