Getting frustrated 😡

Ladies, I need some encouragement please. I'm 36 and hubby is 33, we've been trying to get pregnant for 5 months and nothing is happening. We've tried Softcups with/without BDing and Preseed. My GYN wants me to do a HSG now and hubby will do a semen analysis. He did this last year (which was normal) and I've had all my bloodwork done (also normal) as a part of our preconception checkup. 
I know many women have tried for much longer, so I'm not downplaying that. How do I stop these feelings of frustration each month when I discover I'm not pregnant? I feel like I'm a loser and a failure. I know getting pregnant after 35 is difficult, but honestly I didn't realize how hard it is to get pregnant. This sucks.Â
