Is it me or the hormones

Okay I'm pretty sure I'm over reacting but small things like making a car payment....every single month my cards which have the funds is denied and I believe it's their computers because when I call the bank they say no doesn't look like they attempted or processed and there's no flag so it should go through....I don't know how I dealt with this before pregnancy but now that I'm pregnant I want to scream and throw a tantrum because I'm beyond frustrated that something so simple turns into such a complicated ordeal that takes 4 hours to resolve! I want to cry from being so angry and I'm at the point where I'm about to trade my car for one with an easier payment process! Ugh I'm not sure if my expectations are so unreasonable or that my hormones are making my emotions extremely strong....help 😞😭
