How have you stayed positive??

This is month 3 for me actively TTC. Now just a quick background. I was diagnosed with fertility issues a little less then a year ago and finally was approved to TTC 3 months ago. So even though we weren't actively trying it's been a roller coaster of emotions trying to get healthy and not knowing if what I had going on was going to make TTC really hard or not. I was totally fine the first month TTC when I got my BFN. But this last month it hit me harder. I'm on month 3 now and I'm having a hard time staying positive. I didn't think it would be this hard emotionally so soon! Anyone have any advice on staying positive? :(
