Do you ever worry excessively?

I have general anxiety.. As such minor concerns become really big concerns. For a couple months I've been baby crazy and even though we're not trying yet I'm worrying I'll find out even though I I'm clearly ovulating (based on my temps) I'm in fertile for whatever reason and can't have kids. Because of this even though I have personal goals like getting on a mostly plant based diet and getting in good shape first, I get sad every time I have my period. :/
