Fully expecting some backlash here, but feel like I need to vent, so...

My wife of 2 years (7 years together) has always suffered with anxiety, but recently it has become a lot worse - several factors such as work and a wonderful new addition to our family (baby girl) has contributed to it.

Honestly, I'm struggling to stay sympathetic to her issues. I've always tried to empathise with her, even when I couldn't see why she would be anxious over that particular issue. But recently, I can do this less and less. I just can't understand why she would get anxious about totally innocuous situations. To anyone without anxiety, they would say it's completely irrational.

Truthfully, it's starting to affect our marriage - as I get older, I'm starting to question why I should live a life of walking on eggshells. The kicker is that she refuses to get help/see a therapist, so it often falls on me to help her through her episodes, even though I'm absolutely not equipped to do so, I often end up making her feel worse when I inevitably lose my cool and snap at her or walk out cause I've had enough.

I'm not sure if I have a particular question about all this, I know I'm supposed to be calm, not try and 'fix' her aniexty etc., But what am I supposed to do? Does anyone else find themselves in the same situation?
