Frustrated and Sad

I feel like I'm going to start my period, don't have high hopes this month... been going through a lot lately, my Dad died unexpectedly in June, he was young and we were very close. I've been having anxiety attacks and not sure if that's affecting anything. We have been trying for a year and a half. I feel frustrated like nothing can go right. Not sure if anyone else out there has feelings of loss or stress that may be causing you not to conceive... I just want something to look forward too since I feel broken and it seems like a distant hopeless dream, just having one of those nights...
