Confusion and frustration.

I am struggling to get pregnant since my first five years ago. I've had two miscarriages and doctors suspect endo. I have an appt tomorrow with a new doctor so here's to hoping he actually helps. I am frustrated with all of this to the point I've starting wondering if it is even worth it to try again. I want another baby but some days I feel like I don't. I think I'm just so worn down from daily pain and fertility issues that it is negatively affecting me that way. Is there any way to find positivity through this?
